Theme : Values – 1973 Citroën SM (Very) Long Term Test

As the ever quotable Oscar Wilde wrote, a cynic knows the price of everything and the value of nothing.

As prices have escalated over the past three decades, that aphorism certainly applies to many contemporary classic car collectors. If you have an interesting looking car, people come up and talk to you about it. My Citroën SM is now entering my 21st year or ownership so, over the years, I’ve got reasonably used to this, though my social grace occasionally lets me down. Sometimes the speaker is highly informed and might tell you something you don’t know. Sometimes they are like-minded enthusiasts who just want to make a pleasant comment or know a bit more.

Sometimes they just want to ask the same pointless questions – constantly re-occurring are is that the one that goes up and down / the headlamps turn / has a Maserati engine / Burt Reynolds drove off the dock in The Mean Machine? These questions all get a polite but terse Yes, but the two questions I find it more difficult to answer are Is that a classic then? and How much is it worth?

What exactly is a classic car? An old master isn’t just any painting made before the 19th Century, it also needs to demonstrate the skill of the artist. But, providing it has survived the ravages of rust, the most cack-handed Hillman can be presented by its proud owner as a classic car. I’m not really making a point here, I don’t begrudge anyone the right to think of their loved car as a ‘classic’, even if I might not agree. Certainly the idea of a classics committee that someone who has spent 5 years restoring a Morris Marina would have to prostrate themselves before in order to beg for inclusion into their hallowed ranks would be highly unpalatable

But it still remains an essentially meaningless term. Vintage, Edwardian and Veteran all have defined years, Classic just means that, at the far end, it’s none of those and, at the near end, you can’t find one new in a showroom today. If you try to define it closer than that, you step into a world of subjectivity. So, whatever I really think of its position in the history of motoring, if I concede to someone that my SM is a classic, I’m suggesting that someone else’s Avenger isn’t. So my general answer is it’s just an old car and they walk away disappointed.

In fact my Citroën was supposed to be a Morgan, and two more contrasting cars would be hard to find. In the wake of 1992’s Black Wednesday, old car prices had taken a battering, and were still waiting to recover. Throughout the 80s I’d watched in disappointment as a yuppy feeding frenzy took cars I’d once thought I might buy further and further from my grasp. But, once again, it had become a reasonable proposition to purchase something interesting at a sensible price.

On an unseasonably warm Spring Saturday in 1996, I test drove a 12 year old, Old English White, Fiat twin-cam engined, Morgan 4/4 4 Seater with my partner. That evening we decided to buy it, but a casual look through the Classic & Sportscar back pages showed a garage in Ripley, 30 minutes away from home, with an interesting choice of vehicles, including a Citroën SM, a car that had always fascinated as much as, for a home mechanic of average ability, it terrified me.

Now follows a short synopsis of the Citroën SM, based in part on the various nuggets I’ve been asked to impart to bystanders during my ownership. You can skip this part if you wish.

Introduced in 1970, the SM was a result of what was, in essence, a vanity project of Citroën President, Pierre Bercot, the purchase of Maserati. Citroën had been considering a GT type car, which might also morph into a 4 door DS replacement since the start of the 60s but access to Maserati’s engineering genius, Giulio Alfieri, allowed them to commission a suitable engine.

The 4 cam, 12 valve, V6 was a new design, it wasn’t made by sawing a couple of cylinders off a V8. Since it did, however, suit to use Maserati’s existing machine tools which were set of for a 90 degree V angle, that was used for the six rather than the better balanced 60 degrees. Originally fed by three carburettors, in 1973 Bosch electronic injection was fitted boosting power to 178 bhp.

Despite the existence of the 7 litre Oldsmobile Toronado, in its time the SM was the fastest front wheel drive car in the World. The engine was mated to a modified DS gearbox, with a 5th gear, and with an automatic option, plus 3 litre engine, becoming available later. The Maserati engine was the only engine Citroen offered in the SM. There are some turbodiesel conversions using a 4 cylinder engine made by the resourceful garagiste, Georges Regembeau who also claimed to have extracted 300hp from some of his blueprinted versions of the Maserati V6 petrol engine. 

Suspension was derived from the hydraulic system of the DS but with slightly harder settings – a relative term in the case of an old-school Citroën. New was the DIRAVI steering, with two turns lock to lock, where power assistance diminishes with vehicle speed, with automatic self-centering and which, in normal use, has no mechanical connection between shaft and pinion and thus, no real feedback.

The whole car was built to a far better standard than the DS, with thicker steel and high quality alloys, the downside being a weight of 1450kg. The car styling was by Head of Design, Robert Opron, said to be working with independent design consultant Henri de Segur Lauve (who’d had a distinguished career at General Motors), and, without any hint of retro, it shows itself a conceptual descendent to the pre-War French streamliners.

All official UK SMs sold were left hand drive. Although the SM was sandwiched into a string of ambitious projects – GS, Comotor Wankel and CX – that, ultimately, overstretched the company and led to the takeover by Peugeot, it was hardly a sales failure. It had a rocky start due to timing chain failures caused, in essence, by Alfieri’s over belief in himself – in fact the fix to the tensioner was very straightforward. But over 13,000 were built between 1970 and 1975 and, although its demise has been put down to the fuel crisis and unreliability, hindsight shows us that Peugeot were never comfortable with Citroën hogging the limelight.

Basically, no tears were shed by the grey men at Souchaux when it went and, in fact, there had always been a faction at Citroën who considered it an unnecessary distraction and, objectively speaking, history makes it hard to disagree. The car was never officially called a Citroën Maserati, the only place that the Maserati name appears is on the engine covers and, possibly, in the second letter of the model designation which might, or might not, stand for Série Maserati. And, yes, it is the car that Burt Reynolds drove off the dock in The Mean Machine (AKA The Longest Yard).

Sunday was also a nice day, so we drove down to the garage and looked at various interesting cars on the forecourt, including a 1930s Singer and an early Porsche 356 (surprisingly affordable back then, though the paint was suspiciously thick and shiny), but the SM was not to be seen. On enquiry we were led into a showroom section where a dark blue SM sat forlornly on its stops, its bonnet dull with bubbling paint along the leading edge. This looked an intimidating ownership prospect, made even less attractive for me by the fact that it wore vanity plates ending SM, something I’ve never understood or wanted.

Really we’d only gone down there because it was a sunny day and I was about to make my excuses and leave when the dealer told me the history. Owned from new by a Citroën dealership for 16 years, then sold at the height of the 80s classic boom to a collector, who’d just run it back and forth from annual MOTs, it had done just 24,000 miles and was being offered at half the price it had changed hands for seven years previously. By now I was sitting in it and the dealer asked me if I’d like to look under the bonnet.

“If I look under the bonnet, I won’t buy it”  “Would you like a drive then?”

He got the keys, we got in, he started the engine, pushed the throttle and I heard the Maserati V6 come to life for the first time as the car rose. We went out into the road and he drove us up to the roundabout, once round and back towards his lot. We talked and I guess I established myself as responsible and serious because he stopped, got out and told me to take it off for a drive. This was the killer sales move. By the second corner I knew I wanted it. Although I recognised the definite kinship with various Citroens I’d owned or driven in the past, as a complete vehicle it was unlike anything I’d ever driven yet, despite what you normally read about the SM, for me it never felt anything other than natural to drive.

On closer inspection, everything about the car bore out the dealer’s claims. The boot seemed never to have been used, the spare wheel was pristine and the toolkit was still wrapped in its oiled paper. I knew enough to check that its timing chain tensioner had been modified, but otherwise I acted on blind faith. I made an offer for a sum of money I didn’t actually possess, which included the dealer rectifying the bubbling paint, and we were taken over to the local pub to celebrate our acquisition. I then went off to carry out the rather essential business of arranging a bank loan to pay for it and I picked it up the next weekend.

SM lore says drive a good one you’ll never want anything else, drive a bad one you’ll never want one at all. This was a good one, but obviously not perfect. Getting up to speed on an unevenly surfaced stretch of motorway caused the car to start bouncing oddly then, coming in to London off the M3 and climbing a curved flyover at 70, the front hopped disturbingly to the right over an irregularity. I decided not to put off any longer the inspection by an expert that a sensible purchaser would have done before he wrote the cheque. The result was that the front spheres were shot (an affordable and easy replacement) and that, beneath the dull paintwork and the wrinkled cloth upholstery, whose underlying foam had delaminated, it was probably one of the most original SMs in the UK and in excellent condition.

There are two problems with a timewarp car. First is that low mileage is not always as good a thing as it seems. It means the car has been sitting around unused for months or years on end, and items like seals, that appreciate a bit of lubrication, are just waiting to fail. But, apart from a throttle cable that broke a few weeks into ownership, the main cost was overhauling the air conditioning. This involved a new York compressor and condenser but I was lucky to find a great engineer to do this work who modified the mounting with a brace to prevent unwanted flexing. Two decades on, it’s only now beginning to suggest it needs a recharge.

It took a bit longer before I did the sums and it dawned that it was still sitting on the same Michelin XWX tyres it had been supplied with when new nearly, 25 years previously. Tread depth was fine, and in the dry they were OK, but, driving down off a mountain in a rainstorm, I realised they’d have to go. The Michelins are still produced to order and are horribly expensive, but I bit the bullet and got a new set. This improved things further and, although the car is designed for Grand Touring, it is surprising quite how nimble it can be. Specific to the SM from non-use is the possibility of the original sodium filled engine valves snapping with disastrous consequences, but this didn’t happen and I only changed them for solid valves last year when the engine needed to come out for rear chain and clutch replacement.

The other problem with a timewarp car is what do you do with it – cosset it or use it? With a total production of around 13,000 and over 300 sold in the UK, for me it wasn’t a problem. I had the chance to experience what a near new SM felt like, so I used it and enjoyed it. Over the next few years it piled on the miles, I drove it all year round, for work and holidays in Europe. I was once accosted in the snow one Christmas in Alsace by a guy in a BX torn between pleasure at seeing the car and horror that it wasn’t sitting tucked up in a warm garage for the Winter. This was the first time I became aware that some people don’t approve of the way I use my car. Probably I should polish it more and just use it on sunny days for special occasions. My response is that, although I would take issue with anyone who used a Rembrandt as a tablecloth, the SM is just a bloody car and I’m using it for what it was intended.

Bare metal respray.
Bare metal respray.

My lifestyle wasn’t, and isn’t, that of the original intended SM owner. I live in a terraced house in London and, at the time, I certainly couldn’t afford to rent a garage nearby. I promised myself that, one day, I’d rectify this, but I never have and, in fact, I don’t really want to. I like seeing it in the street and so do other people.

Other people admiring it doesn’t massage my vanity, in fact, as I suggest above, I find people complimenting me on the car a bit embarrassing (after all my name isn’t Robert Opron), but I just think it’s nice that it gives people pleasure, which it does, but in a different, more innocent way from that of a Ferrari, say. As for use, for various periods it has been my sole 4 wheel transport – I’ve used it as a work run-around, for B&Q runs (a bit of ingenuity needed there) and for two long camping holidays in the summer (even more ingenuity required).

My only regret is that I planned to have the car comprehensively Waxoyled as soon as I got it, but was talked out of it by an SM specialist. I understand why he was against it, but had I explained my intentions he might have thought it was the lesser of two evils. In the end, even though I usually avoided very salty days, of course corrosion took its toll. What I’ve learnt about restoring cars is more a list of don’ts rather than dos.

Having painting skills, but not having the time myself, I’ve put my confidence in others and, generally, have not been fully rewarded. Ten years ago I committed to a full respray and, since this would be costly, I decided that I’d change the colour from a sombre dark solid blue to a light blue, actually a pearlescent Audi finish, but an approximation of an original SM metallic hue. This was a bit like suddenly going blonde and, even now, I wonder if I shouldn’t return to my roots. The dark blue has a certain discretion to it.

Anyway, even after the bad detailing had been attended to by the half-hearted spray shop, within a year rust was appearing around one incorrectly welded rear wing and, within a couple of years, the single pack clear lacquer was beginning to blister on the roof. So, five years ago, it received a more comprehensive, bare metal respray which at least used decent materials, though there are still small issues. So, top of my dos and don’ts, if you do want a decent respray, don’t leave the spray shop. Take a sleeping bag and stay there until the job is done. If you find that impractical, then either go to the very best or learn to live with imperfection.

At the same time the interior was retrimmed. The preference for most SM owners seems to be leather. It might look good, but I prefer the feel of cool cloth, so chose dark blue Alcantara. Apart from the non-standard colour, there are other small details the knowledgeable would notice. The dimple on the fuel flap has disappeared (don’t ask), I’ve fitted clear, Italian style front flasher lenses, the rear upper bumper is the more elegant one piece pressing of earlier models and the little aerofoil disappeared from the passenger wiper blade during the respray. Here endeth the pedantry.

The downside of on-street parking
The downside of on-street parking

I’ve always treated the SM like a modern, with little concession, though I hope I’m a mechanically sympathetic driver. For many years I was blissfully able to ignore the car’s age but recently, those minor irritations have multiplied with things like rotting washer tubes and cracking window seals – in essence the car is being betrayed by its rubber. There is also a chronic wet starting problem if the battery charge is allowed to drop too much and a growing tendency to stall when sitting in traffic on hot days, with a grudging restart.  I suspect, this all might be down to aged wiring. But all this can be fixed, and I will probably put my hands in my pockets and do so.

Twenty years ago there was a relative wealth of spares available, with cars coming in from the US to be broken. But now some parts are getting rarer, though there is enough demand for it to be worthwhile for people to remanufacture items like the headlamp glasses, though in acrylic rather that the original glass. There are also a few modifications that it’s been worth having done, such as a larger alternator, a/c cutout and electronic ignition.

The car has shrunk during my ownership. In 1996 it seemed almost as big as it was when launched – at 4.89 metres long it is marginally longer than an XJ-S although, in its favour, you can fit at least one reasonably sized adult into the back of the Citroen. Now, however, it often looks quite compact parked next to something modern.

Sometimes it seems small these days.
Sometimes it seems small these days.

There is a certain type of enthusiast, come to think of it maybe the sort who buys a Morgan, who considers the SM far too clever for its own good. I know what they mean, but I find that attitude unfair. It was launched by a very different company to the Citroën of today, and they were genuinely trying to implement technological innovations in order to improve their cars, not as a gimmicky selling point. Old Citroën was a bit aloof, suggesting a certain intellectual rigour and, often, journalists were a bit in awe of them.

Initially the car had fantastic reviews but, after a few years, once news got round of the car’s timing chains disgracing themselves, the journalistic consensus became that it was probably more trouble than it was worth and, for many, this seems to have stuck. On the other hand, racing journalist Denis Jenkinson, who one might have thought would have found it a bit effete, was a great admirer of the car.

There is still much about the SM that is relevant today. When new it was criticised for the lack of feel to its steering and, indeed, there is no actual feedback at all. But although they might find the immediacy disconcerting, with two turns lock to lock and a 10.5 m turning circle, I doubt many modern drivers would worry about the lack of feel. And, anyway, it still manages to tell you what it’s doing in its own way.


The driving experience is quite unique. Acceleration was respectable for the time, but most similar capacity turbodiesels from the last 20 years could see it off. But then they, at best, make a repressed drone whereas the SM comes with the Italianate growl of a proper engine. The engine was kept down below 2.7 litres due to French tax laws, and it might have benefited from standard fitting of the 3.0 litre fitted to the Maserati Merak. But, in a way, that makes it a car for today’s roads in that you get the aural experience without losing your licence too easily.

Though if you want to lose your licence, it can oblige, cruising rock steady at 200 kph. The gearbox, with its unique rotating gate, is always a pleasure to use. It suits the Italian sportiness of the engine, but is maybe is slightly at odds with the Gallic softness of the chassis and the delicacy of the steering and brakes. A period version of paddle controls would have suited the car well, possibly a sort of updating of the Cotal electromagnetic gearbox fitted to many of its spiritual Grand Routier predecessors.

I like to think that I’m a good driver, by which I mean that I anticipate the road and understand what I’m driving can and can’t do. If we look at a quintessential ‘driver’s car’, as touted by motoring journalists, I’d suggest that it’s something that has a high level of ability, but one that transmits to the driver something of the work it is doing to employ that ability on the road. That transmission, usually defined by words such as ‘feedback’ or’ feel’ is essential because, sooner or later, at the limit, the car is going to bite you in some way or another.

The fact that the driver can cope with this is the way that they measure their skill and derive their satisfaction from having ‘tamed’ the car. This was never the way with either of the two French companies who, in different ways, once upon a time mastered in suspension design, Citroën and Peugeot.

Always photographs well in multi-stories.

Put simply, they thought it best to assume that the driver was an incompetent, that the car knew best and should get on with its job discreetly. Give the car the highest limits you can and avoid any nasty vices, such as lift-off oversteer. That keeps the mediocre driver safe and if, by chance, you are a better driver, you can still exploit the car’s abilities to the full, once you understand its limits. For aerodynamic reasons, the rear track is 200mm narrower than the front and, undignified as it might be with high roll angles, this makes it most remarkably nimble, but in a uniquely Citroën way.

The SM is not a car that you grab by the scruff of the neck and give a good spanking to – you might want to tell it that you’re in charge, but it knows that it is. It doesn’t like the muscular approach. Both brakes and steering require minimal inputs, after a while you scarcely notice yourself doing it. It’s easy to calibrate your body to this and, once you have, other cars seem over-demanding. But if you’re a hand on the roof whilst you grip the wheel between your thighs and lean over to pick up a CD off the floor kind of driver …. then, oh dear, you’re in a ditch. Otherwise it’s a car that looks out for you.

For its time, it has high levels of grip. At one point I economised, switching from the Michelins to that one time affordable staple of classics with odd wheel sizes, the Pirelli P4000. On balance, they’re adequate, but really not suited to the way I’d want to drive the car, not great in the wet and generating an embarrassing amount of tyre squeal in the dry. Also, with large modern graphics on the tyre wall, they don’t look that nice. A switch back to a set of new XWXs three years ago was welcome, if not by my bank account.

An endless gripe is electric windows that need to be booked a month in advance – this is a shortcoming from new – and the swivelling headlamp mechanism that, instead of the mechanical system on the DS, uses a clever enough mini hydraulic system, but one that, like the window winding mechanism, seems to have been built from a home hobby kit. The Mazak door handle mouldings have pitted, the way Mazak mouldings do, which is a pity, but much of the rest of the brightwork is, in fact, stainless steel so it remains in fine condition.

A minor pleasure to me was discovering the ingenious rain-sensitive wiper control (basically the circuit was closed by a magnetic coil which, as the wipers laboured over a drying screen, took more current which heated the coil to its Curie Point where it lost its magnetism, thus opening the circuit and stopping the wipers until the coil cooled). However, the insulation on the coil wasn’t intended to last for 25 years and it caught fire one rainy night, was disconnected and has never been repaired – memo to self, this piece of electro-mechanical archaeology needs re-instating. Another weak spot has been the drive shaft for the high pressure hydraulic pump, which has rubber bushes that have failed twice (unanticipated age again), though this had a silver lining of sorts.

Having spannered previous cars, I vowed I would not get involved with the SM, which in truth made me feel a bit disappointed with myself. Stranded in Tooting one Saturday with minimal tools (when drive to the hydraulics goes, you’re dead), I stripped off the shaft, lashed it back together and even re-timed the distributor by ear, pretty straightforward really, but causing me a disproportionate amount of pride.

SM Interior

For me it’s a very comfortable car. The driving position is perfect and the seat cushions are made from a series of separate foam sections which provide independent support for the different parts of your body – though a nightmare to re-trim and guaranteed crumb catchers. The boot is dominated by the large spare tyre. The camping holidays I mentioned above needed a fair amount of hyper-ordered packing. I have a vague memory of once reading that a planned space saver spare was intended to go under the bonnet and that would have freed up a decent chunk of boot space.

Spare takes up a lot of space.
Spare takes up a lot of space.

Last year I finally acquired a set of original style door mirrors – in fact the stock items fitted to my car were original on UK vehicles, a result of the need to fit right and left hand mirrors. If you’re an SM completist, there are two other items you might want. A set of Michelin RR composite wheels and a Continental Edison radio. The wheels, developed for the SM (though Michelin had ambitions to sell them to other makers) are incredibly light but, crucially, look a lot better than the standard hubcaps, which seem rather like an odd aftermarket faux alloy. The radio was the only thing that fitted flush into the centre console of the car – mounted face up, it must be said that the position isn’t an ergonomic triumph. But at a current price of maybe €2,000 for the radio and at least €1,000 each for the wheels, so far I have resisted.

So, returning to the question I mentioned at the start of this piece, how much is my car worth? Actually, the SM market is quite odd. Stagnant for a long time, it seems to have risen relatively substantially over the past 2 or 3 years. So it isn’t easy to pluck out a figure and, honestly, although I have a vague idea, I have little interest. On a broader level the economics of old car ownership are complex. Buy new, and the car has usually shed maybe 3% of its value by the time you get to the end of the road. Ten years later it’s worth a fraction of what you paid. Possibly if you hang onto it for another 15 years its value will have risen again, but maybe not.

Two years after buying the SM, I bought a used Mondeo for almost the same price. A few years later I sold it for several thousand less than I paid and, today, that car doesn’t exist. On the other hand, a modern car might, if you are very lucky, have run near faultlessly for the time you own it – though the Mondeo didn’t. The market has had its ups and downs over the past 30 years but, generally, prices have risen appreciably, with some classics such as Aston Martins seeming to have risen exponentially in value since 1996. So you can think of old car ownership as an investment, but you can also ask the question as to how much your investment will be worth when the internal combustion engine is banned from your country’s streets, or at least radically prescribed, in 30, 20 or maybe just 10 years time.

Depending on mileage you can usually get a classic insurance that will cover a large-engined sports car for the same premium as a small modern hatchback. Maintenance is likely to consume either time, money or both, unless you really have bought it just as an investment, in which case you might leave it in the garage. Otherwise, it’s a false economy to skimp. Even if the car is well maintained, you might still also factor in the inconvenience of occasional breakdowns. As I’ve indicated, no car was ever designed with a life of 43 years in mind and, although some materials will never degrade, others are not so obliging. That said, I’ve seen enough moderns immobile at the roadside.

Would I recommend old car ownership? If you’re asking as a potential investor, then please accept an impolite suggestion as to where you might stick your portfolio. Otherwise it’s an individual decision and it will never be straightforward. I’m not in love with old cars for nostalgia’s sake. I don’t go to get-togethers dressed in flares and a leather bomber jacket pretending I’m Johan Cruyff (a well known owner of the period and, Wikipedia tells me, legendary soccer player), although I am quite good-natured about people who do. I care about the way cars look, but there are old cars that look good and drive like pigs, and I can’t say I’d ever want one of those.

For me, the SM’s rise in value has actually been reassuringly modest, at least relative to other cars that I’d personally judge to be rather mediocre. As I’ve said, it’s not as rare as people might believe, and its rather unjustified reputation precedes it. Also, fun-loving Linda Jackson’s car company of the same name probably does no favours for the image of a car that was once more expensive than some Porsche 911s. But this suits me fine, since I don’t want to start questioning whether I should squirrel the car away in a climate controlled garage because it’s too damn valuable to enjoy.

I have a envelope stuffed with windscreen notes offering to buy it, and I even once had an official from the Jordanian Embassy ask me how much I wanted for it on behalf of ‘his boss’. Flattered though I was, I rather pompously said that it wasn’t for sale, based on the assumption that I’m sure his boss was no fool and the commercial value of the car is so far less than its personal value to me. However, I do keep the notes because, one day, I might have to get rid of it for one reason or another, but I have no desire at all to do so.

Autumn SM

Oh, and if you ask why I was ever considering a Morgan in the first place, that was 20 years ago and I’ve quite forgotten. By which I mean that I still remember driving the Morgan, it was great fun, and I understand their appeal, but the idea of being able to drive the tens of thousands of miles around Europe in a wide range of weathers in the tooth-filling extractor from Malvern is impossible to countenance. I still do have a list (who doesn’t) of the stable of cars I’d own in a world I will never actually inhabit. Some of them, such as the Lamborghini 350GT, are far rarer and more exotic than the SM. But since I will never be in the position to indulge in such an extensive stable, and if I had to make the decision to have just one car from this long list, it is the one that I already own. So I guess that really sums up its value.


With any Happily Ever After story, you end up asking yourself ‘But Did They Really?’ So in the case of the above piece, that I wrote just over six years ago, I feel I should bring the story to its realistic close.

This month has seen the departure of the SM from my workplace forecourt where it has languished unmoved for over two years.  Its decline was due to a series of reasons, but ultimately my neglect. The neglect certainly wasn’t intended, but my various attempts to find a bodyshop that I trusted to fix various issues for a reasonable price in a reasonable timescale were put on hold by Covid. Then, two problems made it undriveable. These weren’t huge, but one demanded a visit on a transporter to the mechanic.  However, in the interim, an issue over which I had no control at all had, nevertheless, made me feel unwelcome at the garage where I had thought I had built up a good relationship over 25 years. At this point it was interesting to realise how much you rely on a good support structure when you own an old car.

All the same, I hadn’t intended to sell. I thought that in time I would find an alternative solution, despite my work colleagues’ impatience. But a visitor to my workplace spotted it at the end of last year, then approached me on behalf of a friend. My initial response was that I wasn’t interested, but they were politely insistent. Even then, I set a purchase figure that I felt was sufficiently high to put them off. Nevertheless, they persisted and visited twice, and impressed me by being both a genuine enthusiast as well as having a high expectation of detail, which boded well for the car’s possible future. During the second visit they made an offer, far lower than my notional figure and I suddenly found myself thinking that they seemed a nice person, that it was probably a fair figure bearing in mind what they needed to do to it and that it would be going to a good home. We shook hands without my even trying to haggle. Then I knew the answer to the question ‘How much is it worth?’

So now all that I have to remember it by is a patch of moss and an LHM stain on the work forecourt, which I promise I will pressure wash in due course. Do I regret letting it go? Not really. I’ll miss driving it, which even after 60,000 miles was always a unique event.  But the past six years have shown me that I live in a different world to the one I had imagined, and I find the person I was, the one that purchased and indulged himself with the SM, rather disconcerting.  Please understand that this is a personal viewpoint, I don’t apply this judgement to the SM’s new keeper, or to other owners of nice cars or other indulgences. However I think that my time of having a car for anything other than transport is over – if only because, after the SM, most other cars seem so underwhelming.

The other day I was driving a Skoda Octavia down a stretch of road crossed with regular sleeping policemen.  The Skoda is a fine modern car, but with each lurch I asked myself what the motor industry had being doing for the past 50 years. Of course there’s a huge list of individual improvements, but in answering the question as to what the total package that we call a car should offer, the industry has been hugely dilatory and sadly compliant to kneejerk copycattery. Once Upon A Time, Citroen were not.

  1. Thanks for that! The blue Alcantara works well and has made for a car that’s a bit lighter. The spare tyre matter is something I wasn’t aware of. It is obtrusive: do you actually take it with you during local driving?

    1. It’s a large, heavy thing to move about and store. For local driving it’s no problem, it’s only an issue on a longer trip where I want the luggage space. I’ve thought of just leaving it out. I’ve not had a debilitating puncture in all the time I’ve owned it, but it would be a difficult size to source easily. Or I could carry around a repair kit I suppose and hope I don’t damage it irreparably. With nice fat sidewalls, it’s far harder to write off an old-school tyre like the XWX..

  2. I’m going to need a bit of proper time to read and absorb this … will be back later.

  3. I don´t think 20 years is very old for a car now. In 1996 it seemed ancient. The SM seemed to me to be especially forbidding even when they were just 25 years old. These days I have a twenty five year old car and it doesn´t bother me at all. What I am getting at is the same point I made regarding the second last Primera and 406. When these cars were new their two-decade old predecessors (if they existed) were frail and troublesome. Now those cars of 1996 are themselves twenty years old they seem very useable. I don´t look at a 1996 Primera and think that´s a fossil. But in 1976 I thought a 1976 Datun was unusable. The SM is still a bit of a challenge, mostly the Maserati engine. I think even when it was new it was a car for the serious owner.

    1. I think maintenance is going to be far more of a problem as todays potential ‘classics’ get older. Although the SM was a very ‘advanced’ car, that was in the way that its components carried out their function. The engine was a derivation of the artisan engines the Italian sports car industry had been making for years, so offers no problems to an experienced engine specialist – though at a cost of course. The suspension is derived from the DS. Most things on the car can probably be bodged in one way or another.

      But the one thing that would be a problem is the ECU for the Bosch injection, a laptop sized box that sits beneath the passenger footwell. Here we encounter the beginnings of the ‘no user serviceable parts’, chuck-it-and-get-another world of modern car maintenance. Quite a few people prefer the early carburetor versions, and I even think later injection cars have been converted to carbs. However, I wouldn’t want to do that. My own experience is that the injection system is excellent. The original injectors needed changing (there is a history of underbonnet fires) but, until the recent problem mentioned in the piece, it always started first turn of the key and was flexible at all revs – none of the complex rituals often associated with old high-performance Italian engines. But Maserati steered clear of injection on the V6s they fitted to the Merak.

  4. Thanks Sean for this brilliant, illuminating review. I’ve always admired the SM since seeing it in my pack of Top Trumps – French Cars many years ago. Having owned a few hydropneumatic Citroens in the 80’s and 90’s, the idea of buying one has always been in the back of my mind but I just wouldn’t have the gumption to actually do it – and now living near the sea in Cornwall without a big enough garage, where everything is coated in seasalt, it would be a terrible idea.
    This review was great because it talked about nitty gritty things usually ignored by classic car reviewers. I’d always wondered about the seats; they look stylish but French cars often lacked lumbar support and seemed designed to slouch in. Good choice of colour too; certainly lifts it over the dark blue and alcantara is much more comfortable than leather (in my humble opinion). Hope you get many more years of driving pleasure from that sublime car.

    1. Mark. Although I generally find classic journalists far more perceptive that those on the modern magazines, they share the problem that their drives are often short and they never have to consider the pros and cos of long term ownership (though it is probably forgiveable that they don’t try and fit an igloo tent and associated equipment into the boot of everything they try).

      A good point about seaside ownership too – my mother had a secondhand Mark 2 Jaguar that came from somewhere on the West coast of Scotland and it rusted even faster than Bill Lyons would have tolerated.

      Richard. I felt Alcantara the best compromise, and in the spirit of the original cloth material which was quite durable, but bonded onto foam that rotted. As from my description, I’m not a great cosseter of things and a wool interior that I inhabited would end up looking very tired, very quickly.

    2. I like the alcantara option too. In my car, I had the centre portion of the seats similarly covered, but with the high rub/wear side bolsters covered in leather.

      I found many of the French seats of the 60s, 70s and early 80s to be very comfortable over long journeys. Those in the R10 were extremely comfortable. The later petal style seats fitted to the R17, R5T and A310 are also very good, even for long journeys. The sprung under-thigh bolsters and adjustable wings work really well. The only thing really missing is the option of adjustable lumbar support, though I’ve not found the lumber support lacking myself.

  5. That was one of the best articles I’ve read on the SM. A great read, and even better to see the car being used properly. An absolutely stunning looking car (well, apart from the rear view which I still can’t quite get to gel) that looks even more graceful in motion.

    I’ve also got a “classic” French 90 degree V6 (located down the other end of the vehicle) with glassed in headlights that most people wouldn’t have used as their everyday car, summer and winter in Europe. It still gets regular use (now re-located to a more car-friendly climate on the opposite side of the world) for simple things such as the weekly grocery shopping, or off to the local hardware store, and even gets used for commuting from time to time.

    I get people ask if I worry about it getting damaged, but the response is always that if I get too worried about using it, I’ll sell it.

    Enjoy the SM!

    1. Paul. Thank you – and I can’t disagree about the rear.

      There’s the cliche about seeing a photo of yourself taken from behind and thinking ‘Christ, is that what I look like?’. Once, driving on an autoroute in Central France, a brown SM came off the slip road in front of me. The novelty of two SMs forming a chance convoy was diluted by the fact that I found the rear aspect of the other car less than elegant, with its fussy chrome and the slight ungainliness of the narrower rear track. But I’ve grown to love it over time.

      Is my sometimes ropey detective work correct in that you’re talking about an Alpine GTA? Actually, I was dismissing an A310 which would be left hand drive and not allowed to be sold new in your neck of the woods, but I believe there are exemptions for historic vehicles. Either way, both of them are highly desirable in my eyes.

    2. Yes, not only do I ensure égalité for pedestrians on both sides of the road but, if I park cleverly, I can lacerate their shins too.

    3. That’s excellent Paul. Apologies, for some reason from something you wrote previously, I got the idea you lived in Australia. I’ll further compound my ignorance of things Antipodean by asking if the legislation against left-hand drive cars exists in NZ as well? Although as I said above, there were no factory right hand drive cars, three SMs were converted to RHD in the UK when new, semi-officially by a Citroen dealer. In Australia, several have been done over the years and there’s a company who offers conversions today – as you might imagine, it’s a big undertaking.

      Incidentally, any time you fancy penning something on the Alpine for DTW……

    4. I strongly second Sean’s last sentence!
      The A310 has been one of my favourites since I saw it as a child. I like its angular shape a lot, and it’s French, too.

    5. LHD in NZ: much less restrictive than in Australia, thank goodness. The rules have changed over the years.

      Once upon a time, there were few restrictions, then sometime in the ’80s I think (after I’d had my Dyane sent over from Italy) it was decided by the powers that be that a permit would be needed for LHD vehicles. Ostensibly this was for safety reasons, even though, according to enquiries I made of the Ministry of Transport and an insurer at the time, no statistics were kept on LHD vehicle accidents. The real reason I’m lead to believe was that they were worried about the importation of significant numbers of American muscle cars, and this was a way of controlling the numbers.

      The rules now are a little complex, but for classic cars or for cars that the personal importer has owned overseas, it can be possible to import that car and not have to convert it to RHD. For new cars, you generally need to convert hem, unless you can get a special interest exemption.

    6. Sean, send me an email, and we can see if something could be worked out about an A310 story.

  6. Fantastic story. I think ‘story’ is the right word, as you give us plenty of insight into the emotions inherent to such a car, as well as the ins and outs of ownership. Thanks for that.

    As for the colour, I think you should leave it as it is. The lighter blue makes a great show of the SM’s elegant surfaces, whereas a darker colour would leave it looking slab sided by comparison.

    1. I did at one time think of it. But there’s the nightmare scenario of finding it used as the transport of choice of the character played by Ray Winstone in a Guy Richie caper movie – or maybe the morally dubious interior designer who gets squashed by it in an episode of Midsomer Murders. I believe one features in Zoolander.

  7. Tanks Sean, what a delightful reading!

    I believe I’d be a bit too cautious to use an SM as an everyday car, adding more than 20’000 km a year in my case. But I’m with you, cars are here for being driven. Once my GS will be back on the road, that’s what I intend to do, also in rain, probably less so when roads are salty – I’ve done that and now pay the price in form of a restoration. That’s also the reason why I’d shy from a too pristine example of any car (24’000 miles would be OK, though).

    1. Quite a few new SMs were sold to main dealers (I assume on preferential terms) for their own use. I believe that mine was one of two bought new by two brothers who ran a dealership in Sussex. Most of its 24,000 miles were done under their ownership but, strangely, they didn’t seem to have bothered to modify the (known Achilles heel) timing chain tensioner. This was done as part of the purchase agreement with the second owner, although he actually did very little mileage in it. He was, apparently, a collector, but whether he just never got to like the car, or whether he just bought it as an investment, it felt as though it was put to one side – though religiously MOT’d. I think I doubled the mileage in my first 3 years of ownership, but then I became more moderate. Last week’s MOT shows 85,700 miles.

  8. I suddenly feel terribly unadventurous. Then again, I do not much fancy the prospect of sitting at the roadside with my young son in the rain due to yet another mechanical malady. Or the inevitable earache I would receive from the wife when the RAC dropped us home.

    1. Honestly, I’ve had breakdowns, but really the only one of consequence was on the first day of a fortnight’s holiday through France. It completely confused a modern Citroen garage (and me) and resulted in our holiday being taken in a VW Vento diesel, courtesy of the RAC (which was a surprisingly excellent car). The SM was repatriated and the problem even baffled the SM specialist for a couple of hours. in the end, all that was needed was a bit of lubrication at the bottom of the distributor.

      But none of these experiences was as bad as the 3 year old V6 Mondeo mentioned above breaking its water pump and distorting its cylinder heads. Yes, it happened remarkably quickly, I was driving very fast, I should have looked at the water temperature more often, but I had foolishly thought that cheapskate Ford supplemented that with a warning light. It didn’t. Thanks Henry.

    2. My feeling is that breakdowns on old cars are very over-estimated. Until a few years ago, my cars were always between 10 and 25 years old. In roughly 300’000 kms with these cars, I had to stop four times because of leaking hydraulic fluid. Interestingly, this happened to my two newer cars (in the 10 to 15 years range), never to the ones that were 20 or more years old.

      Other than that, only one starter failure delayed me once (it didn’t entirely stop me, as I was able to push start the car), but I have to attribute this to my own lazyness, as the motor has been acting up for quite some time before and I never replaced it.

      But things I keep hearing like cars that do not start in certain locations due to electromagnetic immissions, you never have this with old cars.

  9. Sean, thanks for a wonderful piece of writing that weaves ownership with history and also drive feedback – it’s quite unique in terms of articles that I have read on the subject. Even more than ever, I think this is the most ‘exotic’ car ever launched, Lord knows how it must have been perceived when it was first revealed to an unsuspecting public. To be honest, I love every angle. I admire the way you manage ownership of it, and particularly applaud the street parking – brave and incredibly democratic. I’d keep the colour if I were you, it goes with the rather space-age image of the car.

    Thanks again for taking the time to write this, it’s the highlight of the month thus far!

    1. Thank you SV – I’m glad you like it. Having owned the car so long, I found it was surprisingly difficult to actually write about it. It’s the problem I get when someone talks to me about it in the street. They are asking me about an object, and I end up responding about an experience.

      Incidentally, here is a link to Denis Jenkinson’s period report, on Motor Sport’s excellent archive – if you don’t subscribe I believe you have 10 ‘free’ visits.

    2. It’s hard to put it into context. There were other highly ‘exotic’ cars around then. The Lamboghini Espada was, visually and in terms of packaging, the Ro80 was, visually and in terms of engineering. But the SM was different on the most number of levels. Of course a multi-rotor Wankel SM would really have nailed it.

      Today, something like the BMW i3 was unexpected and certainly showed a new direction but, in many ways, it is really not that different from other cars around today. But the SM was born into the world of the Marina and Taunus and, bearing in mind the production numbers anticipated very brave/foolish, over-optimistic/hubristic/ quixotic (delete to your own choice).

  10. Agree with S.V. and the others. Lovely insight into owning and running an SM. I’m definitely still way too much of a coward to contemplate it myself! I always quite liked the tapering rear, it always seemed very Citroen to me. I think your attitude to running the car is spot on-you own it and it’s there for your benefit, not the other way round. I have to (very) reluctantly admit that if I did meet you (whilst certainly not asking about it’s value) I might also be the recipient of a couple of terse yet polite replies. Go easy on me please. Thanks for the great post.

    1. Mick. I certainly hope I wouldn’t bite, though I admit that I have a partner who, although she likes the SM, doesn’t enjoy the attention it receives. So, if she’s there, during any longish conversations, I’m aware of a glowering coming from the passenger seat.

      The only approaches that irritate me are the ones where I’m told authoritatively that : they can’t go round corners / they made 4 cylinder ones too mate / your side mirrors aren’t original / you’ve got the wrong wheels / that glass over the lamps is illegal / they all had leather interiors. Do I lecture Brian Cox about the Large Hadron Collider?

      On the other hand, I’ve met various people who know interesting things, including the man whose brother-in-law sold Idi Amin his SMs.

      When I first got it, I was reasonably self-conscious – it felt pretty self-indulgent -but, over the years, I’ve got used to amiably thanking people who say things like ‘lovely car’. So much so that on two occasions I’ve puffed myself up as someone approached me with a ‘is this your car?’ on to get from the first “well the rear light’s broken” and the second “God, it’s fucking ugly”.

  11. Excellent story – i never noticed the seat belt lock which is a piece of art !
    I remember the SM was available with a Panasonic radio mounted on the roof – i always dreamed, my Xantia had such a radio, so i could feel a bit like driving in a SM…

    1. I’ve never seen the roof mounted radio before. That’s great. Ever since the Miura, I’ve always wanted a car with roof mounted switchgear. The seatbelt clips are original, but you certainly don’t find them on all SMs. Although belts were mandatory by then, they weren’t always factory fitted, so that you could choose between static and inertia reel. I’m dreading the day the catches fail and I can’t replace them.

    2. “roof mounted switchgear”…
      Be careful what you wish for! The DS 5 has that.

    3. Alfa 75 also had roof mounted switch gear. Quite a nice V6 up front too 😉

  12. Thank you very much for this, Sean! I feel like a timid novice in the classic car ownership game in comparison, due to both my car and the way in which I’m keeping it being considerably more conservative than your own choices. Apart from that, I’m now more eager to experience an SM (please note the indefinite article!) than ever before!

    1. I’ve never viewed the XJ12 as conservative, Kris. Some of its originally intended owners, yes, but the car itself always seemed a rather glorious thing to have popped up in the dour Seventies.

      I realise it’s 18 years since the car was in the Hamburg area, plowing up Bundesautobahn 1 in close traffic with 130mph showing until I decided that it might be unwise to put too much faith in the guy 5 metres in front of me in a GTI and backed off.

      If only Editor Simon wasn’t so cavalier with the petty cash, using it to feed his sherry habit, we might be able to organise the DTW Track Day, and you’d be very welcome to drive the definite article.

  13. Phew. Well that was an article of the kind of high quality I cannot remember reading for quite some time. The car, well. Let’s face it, nothing since has really matched it, and modern electronic doo-dads and a rock hard ride do not compensate for the hydraulic system, single turn lock-to-lock steering and that clever instrument cluster. And the looks. My, the looks always overwhelm me.

    The first one I ever saw was not far from the All England Tennis Club, Wimbledon, parked on a short shopping parade in summer 1971. Beige metallic, almost pinkish in the sunshine somehow. I let everyone else walk on while I just spent some time taking it in. Ridiculously avant. Fantastic. The profile, amazing, never been bettered by anything, as in the photo showing someone else’s unconcern at grazing its flanks.

    Glad it is enjoyed daily.

    1. Thank you Bill – but I’ve had 20 years to write it! The flank grazing was, amusingly, carried out by a (vaguely Morganesque) Panther Kallista, whose owner chose not to stop (I suspect the fact that it was Sunday afternoon, the sort of time that unreformed folk finish their pub lunches might have had something to do with it) but was spotted by a vigilant neighbour.

      The first SM I saw was in a Citroen garage in Hampshire, but I tend to think of the first one I saw as being one actually on the move. That was in 1974 on a corniche road in the Cote d’Azur. I was driving my knackered Bedford Utilabrake, nine up, coming back from Greece, to find myself held up by an opal green SM driving at around 50 kph, oddly indicating right or left as the road curved right or left. As I unleashed the full clattering force of the Bedford’s 1600cc to surge past, I looked out to see a wizened Picasso like man driving a statuesque blonde woman, who was, probably, at least 40 years his junior. I wonder how he managed that, I thought. Well, today I can tell you – it wasn’t the car.

  14. I’ve spent rather too much of this afternoon reading a copy of pre-Boring Boring CAR, from December 1995, in which Pierre Beauregard states:

    “That wonderful car was killed off prematurely by Peugeot more out of jealousy than economic necessity. Coachbuilder Heuliez produced studies for a CX-based SM that would have cost very little to produce, but the new masters did not want Citroën to have a car several classes better than any Peugeot.

    So literally thousands of already built SM bodyshells were crushed and melted. Looking at perfectly kept SMs now, one deeply regrets that vandalism.”

    I’m sure we all share Pierre’s view on the matter, but literally thousands?

    Only 12,290 SMs were produced from 1970-75, and a total of fewer than 500 were sold in the final two years, but that sounds like shockingly poor housekeeping. Can it be true, or is Pierre indulging an a bit of Gallic hyperbole?

    1. I think that the ‘killed of by the fuel crisis’ thing is certainly a myth. Relatively speaking it was one of the more economical large GTs after all. When the SM was still in production, I remember reading Pierre B’s predecessor at Car, whose nom-de-plume escapes me, saying that the CX front could easily be fitted onto the SM. That sounds rather simplistic, but I’m sure it could (should?) have been saved. I was always reasonably tolerant of Peugeot’s smothering of Citroen – whilst they actually made very good cars themselves – but these days I find it odiously small-minded. Yes, ‘thousands’ sounds unlikely.

    2. Further to than, in his book Sa Majeste, Peter J Pilman says the rumour was that ‘dozens’ of bodyshells were destroyed, but there’s no confirmation. Against this, he also recounts that after he’d left Citroen, Robert Opron was told that PSA had 14 brand new SMs stored somewhere, and that in the mid 80s a friend of Opron contacted Citroen and bought one. Got any left Ms Jackson?

  15. There was another apocalyptic (but possibly apochryphal) story about complete SM engines being thrown out of a fourth floor window to put them beyond use, and thereby make it harder to keep the surviving SMs going. Used as a demonstration of Peugeot’s ‘Stalinism’, but believable.

    Jean Bellevue is the name which comes to mind for Beauregard’s Oracle predecessor, except he was Beauregard’s successor. I’ve just checked, and Oracle began in June 1976. Pierre was there at the start. Possibly both were noms de guerre, useful when you are breaking press release embargoes and reporting stories out of school from disloyal insiders.

    1. I’m not sure I find that so credible. After all, the penny pushers of Peugeot would always put a balance credit before pettiness and, surely, they could have cut some sort of deal selling them back to De Tomaso to put into a variant of the Merak.

      If Beauregard came before Bellevue, then it must have been Pierre who claimed the CX front would bolt onto the SM, because I seem to remember there was a ‘french correspondent’ around before Oracle appeared. Unless that was Paul Bonperspective.

  16. Hi Sean. Great car, great article! I have a roof radio console for you, if interested!

    1. The one feature of my SM that I have always hated is the rubberised plastic low-rent feel of the steering wheel. I have just treated my wheel (and centre boss) to a professional wrap in leather. Best £150 odd I have spent on her.

    2. Hello Julian:
      Thanks for your message! The thing I want to do to my car (an XM) is to replace the leather with something entirely richer like a dark green velour. It’s not going to impress purists.

  17. Starting at the tender age of 6, I spent 3 years in the back seat of two consecutive SMs, the first a bright green metallic (my favorite) and the second a dull brown metallic (effectively killing all attractive highlights of the body). My dad has over the years often remarked that he should have owned them simultaneously, to have one on the road and one in the shop (this was 1972, so mechanics took their good time to understand the car). He bought the first one when seeing it being towed into a Citroën mechanic’s yard with the right wing missing… the architect who had bought the SM new was totally sick with its needing repetitive timing adjustments as well as it spontaneously dropping essential bits (said wing) on the Autobahn. I loved the car to bits. The brown had only one thing going for it ( for a kid), as it sported a phone between the front seats (a proper bakelite one) which I played with and proudly displayed to other motorists…
    I now drive one of very (!) few Avantimes in Sweden, having an SM moment all of my own. I probably should get a second one, to have one on the…

    1. Thanks for stopping by Jesper, how fortunate to have had the experience of such marvellous cars at such a tender age. The Avantime must be quite something amid the Swedish landscape. Clearly the formative experiences rubbed off…

  18. Hey Sean. A great post on the SM that I’ve only just stumbled on here in Covid ravaged ‘21. I love the fact tha t she’s your daily driver, rain or shine, and not a heated garage queen. Trying not to sound like a stalker, I was curious as to where you live after reading about Tooting in the post. I mention this as I’m in Balham and with a future SM purchase ‘top of mind’ (before prices spiral out of reach) I’m keen to meet experienced owners who can talk me around their car so I know what pitfalls to look out for. Knowledge is everything. So, if any SM owners live in or close to London (or Whitstable, Kent) then do let me know ( On the off-chance that there’s a few Nick Cave fans out there, I’m convinced that the only car to fulfill Nick’s gutteral lyric “I’m driving my car down to Geneva’” from Higgs Boson Blues (on the seminal album Push The Sky Away) is an SM. Tom Ford shades, a smart shirt, patent boots, an unwaivering desire to just drive, and time to kill. Classic!
