Ebay Motors is a good place to look. I steered you wrong earlier. You want a C-6. 2005 or newer. Not sure what I was thinking.... You can do a search with all kinds of filters to find what you want in your price range. If you wait till spring, I plan to go on a road trip looking for one.

But seriously, test drive the GT-R. That's the most incredible car I've been in a long time. What makes it so damn fast (other than a 3.6 0-60 and, 12 second quarter and +1 g cornering) is it's super smart and driver friendly, IE: any idiot can drive it well. Too well in many cases. It's compared to the 911-GT3.
