on a track the 599 would murder a SL65
Damn straight! AMG put the wrong tranny in the car, they had to rush and didn't want to wait for the 7 speeder, so they put the 5 speed one that could handle the 700+ lb feet of torque.
And it is still a heavy car, even after taking 200+ pounds out of it.
MB, the 964 is my favorite Turbo, all black please.
