Poncho, that's why I brought up the Chrysler products in response to the frame vs unibody issue. All Mopars, whether designated as a muscle car (medium sized car with "full" size engine) or pony car (built to compete in the Mustang market), are unibody cars, so the people who cling to the "frame" idea are really grasping at straws to defend their cars. A better distinction might be a wheelbase of 110" or less.
Challengers are pony cars, 110" wheelbase, Cudas a little shorter at 108".
