Not. Really.
The 911S and the base Corvette w/ the Z51 handling package are about equal performance-wise. Vette wins on $20K lower price tag. 911S has snob-factor advantage, but not worth $20K extra IMHO.
Z06 and 911S are about the same price range, but Z06 KILLS the 911S in all areas.
Z06 Vette and GT3 are pretty much dead-nuts equal and a race on a road course would come down to the driver. GT2 and Turbo will walk the Z06, but they should. That extra $30K has to buy you something.
Now, the ZR1? Its performance MURDERIZES the GT2 and Turbo, and even bested the Carerra GT at the 'Ring by over 2 seconds.
Lap times and performance figures are facts. Subjective opinions are entirely different. You can like the Porsche's build, fit & finish, etc. You can be in love with the 911 styling. You can hate the Vette "image" and "look" if you want to be a sucker for stereotypes. It doesn't matter. It's all your opinion.
The FACT is for the money the Vette, from base, Z51, Z06 up to ZR1, is the best buy anywhere. Period.
where's this info from because I read an artical in I think road and track while in the doctors where they were comparing the GT a Ferrari, Lambo and the ZR1 and although the ZR1 was competive performance wise (not the front runner) it got last place in everything else.
maybe a little more but I'm sure resale plus life of car is worth the extra price.
