In my opinion (since other guy did it lol)

Retro-success
Mustang
Challenger (should as long as they dont totally fuck it up like they did the charger post concept)
GT(40)

Failures
Charger (a 4 door "muscle" car is fine... but dont call it a fucking charger, a charger is 2 door...)
GTO
and I honestly dont see the new Camaro having much success seeing as how it's butt ugly... the taillights look AWFUL heh.
