BMW 6-Series Gran Coupe
The main German rival of the Mercedes Benz CLS, the BMW 6-series Gran Coupe is a graceful sedan. Where the 5-series is fat and bulbous the 6-series Gran coupe is thin and elegant. In profile, the 6-series has a very low slung, almost sports car profile. From any angle, the 6-series is striking to look at — sort of stops your heart.
