WOW... look at the size of rear-door, it's so small, especially at the base of the door. Very coupe-like!
Actually, compare it to the CLS rear-door, it's nearly identical.
Good thing is, BMW won't call the 5er a coupe. If you want to see the gradual coupe-like transformation of the 5er, just compare the Hoffmeister kink on the E39 5er that klier posted with that of the F10 test-car! A totally wicked change from restrained elegance to all-out sporting charisma!
