Talk to a BMW designer and you’ll quickly learn that the 2007 3 Series Coupe shares but one exterior component with its four-door counterpart: the door handles. Given the different body styles, that may not seem terribly significant, yet consider that even the details have been tweaked for the Coupe. For example, the wide taillights with their horizontal LED displays are unique, the headlights have been slimmed down with the now familiar rings serving as daytime running lamps, and the front fenders are constructed from a plastic composite to save weight.
