You must have your launch down pat. Was the M3 a manual as well?
Also, what happened with the C63? Did the guy just lay down all of his rear tire rubber at the start line?
I was actually behind one the other day while there was a small drizzle in moderate traffic on a surface road. The guy was driving like a complete asshat spinning his wheels and sliding every time we moved. It seemed only a matter of time before he either spun the car or slid into something or someone. Needless to say, I gave him a lot of space and took the first alternate route I could.
They do sound good though.
