technically you are right about the z06, the corvette was originally classed a sports car. That designation pretty much died with the 1967 427/435 though. The viper is the epitomy of muscle. I mean come on a V10 in a stripped down chassis? The only reason it would get a sports car class is because as far as I can tell the muscle car designation is pretty much dead and gone =/
