I agree the 4 door has been the better looking car in current and last versions.I'm with you there Housey...I also didn't especially like the old M4 either (M3 I think looks great, obviously!).
If I were in a position to buy new I'd order this: https://configure.bmw.co.uk/en_GB/configid/2ymzxe5r
(Basically my F80 in G80 guise!). I think the big nostrils disappear quite well into the dark blue.
