The Automotive Icon Carroll Shelby is playing with fire, he is preparing the GT500 Super Snake package for the all new even better looking Ford Mustang and will unleash them onto the road in limited numbers starting in August. Customers can choose from either a 630 HP option, or the ridiculously 725 HP version, priced at $29,495 or $33,495. That is after you buy the GT 500 that wears his name as well.
