I have driven a good friends Z06 on the road. It is a beast but just too much torque. I am so used to high reving cars that I always have a tendency to give too much throttle in super high torque engines. I test drove the Grand Sport which was more to my liking with a bit let power and torque but still great handling and great on the track. I will go with the convertible with the stiff chassis and better lines.
