From the surface, the C63 looks like it has the goods to compete with the big boys in the Euro performance club. Boy racer styling? Check. Monstrous V8? Check. Ginormous tyres? Check. Manual transmission? Not so much. Also not along for the party is a coupe or convertible version of the C63. Mercedes’ decision to make the C63 auto-only is perplexing enough, but the fact that they also decided to ignore the rest of the M3 portfolio is truly baffling. Consider the competition: the M3 coupe and convertible [combined] outsell the M3 sedan almost five to one. This halfhearted approach to a hotly contested and prestige-generating segment truly defines the experience with the C63: you constantly feel like this could have been a great car.
