Rob, you're right. More power would be key, but I'd like to not only see more power, but a special, 'elite' engine only for the Vette. Like an LT-5 to the ZR-1. Something that the other Vettes, [?future] Cameros, Caddys, etc. won't have.
A honeycomb aluminum frame (ala Shelby Series 1) would be very nice, and to be honest I'd like to see things like CD changers, power locks, A/C and other "luxuries" missing. Leave that to the regular Vette, and allow the enthusiast willing to spend big bucks to have a real racer. I'm not in that cohort at this time, but I'd just like to see a really smokin' vette without a bunch of frivilous bells and whistles.
