You may not even have the chance to buy a 2002 Camaro since they aren't going to make them anymore.
If you ask this question on a Camaro board or a Mustang board your going to get baised opinions. Best thing to do is go to the local dealerships and test drive both, a Z28, SS, GT, Cobra.
I asked a similair question two years ago except I was looking at the WS6/GT/Cobras. In the end I test drove each and bought my GT and have never looked back.
