are we talking about the z3 roadster? or the m coupe? the reason why i asked is because i always thought the m coupe was just an m coupe... but this weekend i saw one with a z3 badge on the back... i always thought this a z3 (yellow car) (granted that is an m roadster you get the idea of the basic shape etc of the z3. and i always thought the blue car was the m coupe... But when i saw the z3 badge on the blue car (m coupe) it got all confused?... anyone that can clear this up for me?
