I was never a big fan of the SL because its such a boring car to drive, all looks and little driving satisfaction. Also, the fender vent should've been painted to match the body. However, I can see why M-B decided on a contrasting color for the vent because otherwise the fender would look too slabsided.
I'm sure the 6208cc beast of a motor would make this thing come alive. Either way i'm waiting for the SL65 Black Series to come out, it's going to have a 670hp V12 Bi-turbo motor.
