I'm going to buck the crowd here and suggest that a new Corvette may not be the answer. As background, I've had a 1996 LT4 corvette since new. I've also owned a lotus elise, an E46 BMW, and currently drive an Audi S4. C6 Corvettes are very very fast and nice cars. I looked at several before I bought the Lotus. I found that the C6 was just too fast to be fun on the street. On one test drive I accelerated up an on-ramp (hard, but not full throttle) and was going 120+ at the top of the ramp. I find it much more fun to drive a slower car fast than to just be puttering around or scaring the shit out of myself in a faster car.
Anyway, I feel like I now understand people who opt for slower, but more "refined" or "interesting" cars.
Anyway, good luck with whatever you choose. I think the Corvettes are great cars, just awfully fast to be fun on the street.
