I think you'll regret not waiting for the 2006 Z06. That'll give others a year to shake down the semi-new design while the finishing touches are put on the 500+ hp engine and lightweight frame and body. The Z06's hold value better and I thought I read that it'll be available for the first time in both coupe and convertible, but I might be wrong about that. There are some very knowledgeable enthusiasts over at
www.corvetteforum.com, and some good deals on used cars with full histories.
