yeah, I always read that the gtr was supposed to beat the z06, which it did. Then they came out with a car that is like 40k+ more and bragged about beating them? Im not downing any of the cars as I would own any of them in a heart beat. Just want to give credit where its due. I think the viper wins, hands down. Then zr1 (which I would compare more to the viper), then the gtr, then the z06 (which I would compare to the gtr)
