Interesting this: Wikipedia does not note the existence of the three-door estate. It does list a 2-d00r saloon, a 4 door saloon, a coupe and a five door wagon plus the enigmatic two-door van.
And a picture search reveals very little like this but does show the 5-door estate, and a two-door saloon in some numbers. Is this a Danish-market special? No, but it was not very widespread.
A pair of photos of a 1973 1900 can be found here.
This is another example of Opel’s habit of offering a lot of bodystyles compared to their peers.
Ford didn’t offer a 3-door Granada but did have a van based on the Sierra.
There was an Opel Kadett three-door estate and a Ford Escort 3-door estate. I can’t think of very many other likely cars in this format. Evidently, such demand as there was for this type of car was taken up by hatchbacks and five-door estates. The class is now extinct.
On the ashtray front we find a pretty decent one right where it should be, in front of the gear lever. It seems to be of the flip-up lid type. You can just make out the small flange on the leading edge. In the back a rather fancy chrome-plated lower-hinged ashtray is located on the side trim.
In the push for SUVs and CUVs, we have lost many interesting formats. I can certainly see this concept being sold as a kind of lifestyle shooting brake, something a little lower to the ground with all the useful characteristics of a hatch and a more tractable centre of gravity.
I will leave you with this gem, a 1973 Opel Rekord 1900 coupe.
