I literally JUST got out of my buddies new Black C63AMG. Short and Sweet- Guys.....BOY did we make the right choice to go with the M3! WoW there is NO comparison as far as the overall car is concerned. Low point- the interior is very weak. I felt just like i was in my mom's old C class. High- I must admit the acceleration/torque is unreal. I felt my spleen shift positions w/ a 0-100mph run. Didn't actually drive the car yet but i can confidently say, I would never consider buying that car.
