Congrats on the car, that's a fantastic purchase. Though with how big you say you are, how do you find the seat bolsters? Every C63 I've ever sat in has what I consider to be pretty tight bolsters--great for back road fun, but I question how comfortable they would be on a regular basis. I'm 6'0 and 200 lbs, so I'm not huge, but I'm also not small. Either way though, a big nasty NA V8 should be experienced at least once in every gear head's life---and you certainly chose an excellent example.
