[BM3W!]

I love the C63. That and the Audi RS4 were the two other cars I considered before finally ordering my 08 M3 Coupe.

The C63 will pull the M3 slightly in a straight line. This is fact, however the M3 will over take it in the first turn. This was proven (for all intensive purposes) in the shootout between the M3, C63 and IS-F where by the end the M3 was over 8 seconds ahead of both cars.

The thing that made the M3 my final choice was: (and in no particular order)
The looks
The EDC which allows my M3 to go from 335 like comfort, to a bit stiffer than an E46, to a setting meant for tracking your car. This alone is a huge benefit.
Handling
Stability and Traction controls are light years ahead
6 speed manual - I simply would never want an AT in a sports car. How fun is mashing the gas... I prefer driver skill.
etc.

At the same time, the C63 is one hell of a beast, and I love the sound. Either car is awesome. Enjoy the hell out of that thing, I think its an incredible car and more than worthy of that AMG badge.

Does anyone know if you can chip the car and unlock the 65 or so HP (I think thats what it was if I recall correctly) thats there, but AMG detuned it so it wouldnt beat its highr echelon cars? That would be sweet assuming the AT and drive train can handle the extra power.
