I hate to bring this into the discussion, but as much as I love the C6 Z06 for its performance it does lack in other areas. I sat in a Z06 and a Civic Si at the car show and in many ways the Civic was a nicer car inside. It's pretty sad that a 20k dollar economy car has nicer fit and finish and nicer materials used in the interior than a 65k dollar sports car. My friends actually forced me to sit in both because I was going on about how cool the Z06 was and they wanted to take me down a peg, and I had to admit that the Z06 was actually inferior to a Civic in at least one aspect.
As much as we throw numbers around on the internet, just have to remember that there's more to a car than numbers.
