Go for an '08 Corvette and just add the 4LT option to get that upgraded interior with leather stitching EVERYWHERE. Only put you out 4K.
The Corvette is one amazing car, and I'll agree the interior isn't the best in the world. But it's better than some. I mean come on, the seats are some of the most comfortable I've ever sat in. What more do you want?
Camaro is will be an awesome car, but it looks like the Corvette is what you want. So get the Corvette, and give the Camaro the thumbs up when you see one next to you at a stoplight!
