Well, what's wrong with it? If that's not muscle, what do you want? Educate me, I'm ignorant of such things.
Not ignorant at all -- comparing the Corvette with the classic "muscle car" is like comparing the cutting power of a sword with a broadaxe. Both cut, but the lighter faster sword (i.e., the Corvette) has a level of finesse; the broadaxe cuts with sheer power.
The engines in the muscle cars are throatier, louder and far more powerful in a head-to-head competition than the lighter Corvette (and other similar cars).
I used to have a friend from Tokyo who went to college in Chicago. When he moved here (mid 80's), he bought a Buick Grand National (one of GM's last true muscle cars). When his mother (a quiet, reserved woman) came to visit, all she saw was a Buick Regal. She had no clue. That is until people challenged her to race more than once at stop lights...
