What distinguishes an M coupe cosmetically from a normal Z3 coupe?
The M coupe is based on the Z3 coupe body, but adds a more aggressive front fascia with brake cooling ducts in place of foglights, unique side gill vents with the M logo, chrome windshield washer nozzles, curved M side-view mirrors, a lower rear bumper with four exposed exhaust tips and a relocated rear license plate (located between the taillights instead of within the bumper).
