Both the Z28 (modified) and the Lexus 400 are good for better than 150 mph but they will never see it. Much too dangerous for me and especially anyone else on the road. Anyone can drive in a straight line at high speed. The true analysis of skill is at the track or strip. There acceleration, lateral g's, torque management and braking come into play.
Also, most speedos on cars are very optimistic.
