The 350Z's are pretty nice as well as the sport G35's (probably built on the same platform being owned by Nissan and all). OMG they look so fine!!! Raw power. For modifieid compact sport, SRT-4, EVO MR, STI are tops.
I find the Corvette C6 to be the best bang-for-your-buck car on the market. It's just so nice, plus it has all kinds of new goodies, if you've ever been in one, you know what I'm talking about.
