The dashboard doesn't look right to me.
No, It doesn't. I'm guessing this car is based on one of the later versions produced in the 90s. The classic mini dash was near non-existent. My first car was a mini clubman, maybe 1980.
Yes, the first Mini dash was, I think, just an oval in the middle of the car with a big speedometer flanked by a small dial either side. A girlfriend of the time had a red Mini but my memories of the interior are vague as for most of the time I had my eyes tightly shut! I seem to remember that the Cooper version had a large rev counter mounted on the steering wheel housing, but I may be thinking of another car.
Yes, this is definitely based on the later models. The placement of the dashboard features are actually quite spot on for the later ones. The earlier models have essentially just a centre instrument "binnacle" as you note. Also, the tail lights, side windows, grille, and the lack of external door hinges show this to be a later model. I like the subtle styling differences of the earlier ones a bit more, but the later ones are cool too!
I think the klickies are supposed to be in 1960s garb.
It certainly does look like that, but I doubt many will notice the period differences between the figures and the car!
