I have the SS!
I'll bring it out this Friday night. It's an SS/RS so visually it's basically the same as the Z28. Only difference is the badges, the hood, and the stripes. Performance wise the 302 in the Z28 is better. Of course you can always stick an LS1 in and then it doesn't really matter.
I also have the F430 Scuderia and the '07 Gallardo Superleggera.
