Well Ford should make a 500 hp Mustang in the same price range. Shelby GT's cost around $100grand, with a little more hp. I would put a Z06 Vette up against a Ford GT. They have almost the same hp, but the Vette is lighter. I bet it'll be close, and wouldn't cost over $100grand. The 2011 Zo6 Vette, all carbon fiber, 6 speed trans is $63grand. So, with price and performance--Chevy Rocks!
