Based on looks alone, I'd prefer the vette.
But instead of buying new, why don't you find a lightly used c6 convertible vette instead of new?

Then you can add some fun stuff....like good exhaust:
" onclick="window.open(this.href);return false;
or maybe a supercharger:

and probably be in the same ball park money wise as a stock, new vette.
