Well consider me unbiased because I like Mopars. But I know the Z06 Vette is a tad faster. And will also outhandle the stang. Sorry Ford guys
But as far as price=performance I would go with the SVT cobra. Just do a couple of mods that will still equal way less than the price of a Z06 and the Stang will outperform the Vette in every way. Sorry Chevy fans
Just get a Viper and call it a day.
