I bought my Cobra brand new and have never driven a Z06 but I voted for the vette. As much as I love the Cobra, I'm seriously looking at the Z06 in addition to. The Cobra, as much as I want her to be, is just not refined in any measure. She is the F4 of the muscle cars, big, heavy and powerful, but would never be confused with an F22 Raptor. It's all good and you really can't go wrong if you can swing either one. It looks like the prices are closer than they've ever been so that should be a boost.
