Our visiting Saab experts can probably identify this car more precisely. It lives near my home and comes out at the start of summer and disappears in the autumn. It never seems to move in the meantime. I think it may be a piece of conceptual art.
The timeline for the Saab 96 shows you could buy a new one until 1980. Similar living-fossils such as the Mini, Beetle, Renault 4 and 2CV all existed into this period so the 96 was not so out of place. However , the 96 must have seemed very archaic compared to the Golf which in many ways shares the same layout though the Golf´s engine is longitudinally mounted instead of being transverse.
If you were in a retro frame of mind you could do a lot with the themes and elements of the 96 and style a rather splendid C-class car.
Saab paid a lot of attention to aerodynamic for this and the 99 and then 900. After that they seemed to give up on the idea in any overt way. By the time Saab died (sort of) a few years back their cars had grown enormously such that the 9-5 of 2010 was a 5 metre long luxury car, quite out of keeping with Saab´s ethos. I always felt Saab would have been better to look to this car and make something more robust, spartan even, in the manner of a 911 but in the Golf/Astra/Focus class instead of trying to outdo BMW et al.
