Welcome to the forum jmath. I have owned 3 vettes but none of the recent models. If the n/a crossfire is not fast enough for you try looking at the SRT. These cars were built in limited numbers in 2005 and sold in 05 and a few in 06. They come with 3.2 LT AMG supercharged hand built engines that makes 330 hp stock at the crank. With some bolt on mods (see Needswings.com) and an ECU tune 350 rwhp is possible. In stock form the SRT is a 4.7 to 4.8 0 to 60 and a 13.2 1/4 mile car. Some members here have broken in to the 11 sec 1/4 mile times. With the price you can get an SRT for these days I don't think you can buy more bang for the buck.

I am sure others will respond that own n/a models and tell you about their cars. Take some time to read about these cars, there is a ton of info to be had here.
