I havent driven the C63, but the sound of the engine upon just revving is pretty sweet. Apart from that, I don't like the styling of the C63. Interior and exterior looks like a regular C350. I once saw a C350 w/sport package and C63 next to each other at the dealer and had a hard time telling the two apart (And I'm a pretty detail oriented person). However, if you're doing mostly city driving and in traffic, the greater torque of the AMG would be nice.
One thing I didn't account for when getting the M was the gas mileage, it's atrocious. Putting gas in this thing is like having a second car payment. The C63 is worse, so I can't imagine what that would be like.
