My wife and I had 7 BMW's (1, 3 and 5 series often with 6cyl engines)... So suppose we like them ;-)
The most fun was a 130i.
Always have loved their ride compared to the other cars in the segment. Having said that, never owned a BMW M.
Although I think that the M4 you're presenting looks quite good, I've the impression that their cars, with some exceptions, not age well.
The thing is, if I would buy a M4 now, I would like to keep it, and in 20 years have a youngtimer. And I don't see that happen (yet).
Btw, thx for all the great pics.
