I like it. Is it the car rental forecourt or a dealership? I have a similar shot in my old archives, except it was a dozen Z8 convertibles.
Very nice photo and perspective. I like the angry-looking clouds a lot and they do add to the sporty, menacing appearance of the front end of those M1's. They should be a great driver's car.
It is a stout little car. It is quicker than the M3 on a smooth road. However, the suspension is more like the old M Coupe, which is to say uncompliant. It gets very entertaining on a lumpy road or a wet one.
No I have not driven it, but there was a driving test in Auto Motor und Sport. They made the reference to the old M Coupe, which I drove for 40,000 miles before switching to an M5. The M Coupe was a lot of fun, but hard as a rock, and if you were putting power down, in anything but a straight line, it did not take much to unstick the rear. I your german is not too rusty you can read the M1 test here.
