Are we comparing drivetrains or looks. Off course RWD is greater then FWD hand down in my book. However, as far as style goes I think BMW went a bit conservative and MB went a bit too bold. Except for rear taillights and droopy butt I like the rest of CLA design theme. I think it is a bit aggressive and more sporty looking then M235i. I think BMW is lately designing very conservative cars. They need to be a bit more aggressive and sporty.
I am looking forward to M2 and CLA AMG that is rumored to be AWD.
