My 2012 C-63 is NA. When you buy one they comp you for their one day performance driving school. Mine was at Leguna Seca. You drive the crap out of everything but the S class and G-wagon (both of which I do not care for). All of the turbo charged cars (E, SL, CLS) didn’t impress me, even with their added hp. I actually liked my car the best (although that was the 507 version), even preferred it to the gull-wing SLS’s.
Got rear ended (no jokes please) last year & I drove a new vette for a month. Immediately I wanted my car back, no comparison, night and day.
Had an NA SRT-8 that I modded and was over 450 at the wheels on a dyno, still no comparison.
Wouldn’t mind trying one of the red-eye versions of the Challenger, but those seem big and bulky.
Tempted to have someone build me a rat rod that can do everything my C-63 can do, but don’t think it is possible.
