Have you all seen the interior of the new C Class? It's practicaly all plastic...
Also, the ride comfort of the C63 is not as good as the M3 for a daily driver m(stated in numerous reviews). Of course there is more torque, but if you shift the M3 higher up on the RPMs you will tap tons of torque....how much do you really need?!?
M3 = Better MPG, Ride Comfort, Styling (IMO), Interior and Options
+ Lease rates for it are much better than the C63....
M3 = Sold
