C63 is to busy design and looks like a ricer. I prefer the more elegant M3 and its proven to be one hell of a performer even if its not a Coupe. 4-door M3 will fulfill my needs completly and I rank it above the other two germans. But of course I rather pick M3 Coupe over M3 Sedan, unless I dont need the space and practicality. Whatever the case is, I certainly dont buy a c63 or a Rs4 over a M3.

Funny someone mention facelift when the front is an exact copy from M3 Coupé.
