Looking good, exactly what BMW need in the range. A replacement for the original Z4, a Boxster/Cayment/Audi TT competitor. Not really interested in anything in the current M range but yes this looksgood.
I doubt it will look remotely like that when it comes into production - too risque... will def be toned down more... especially the rear... that would put a lambo to shame!
The front looks like the new i series cars though - which i quite like!
