I'd say go for the Camaro SS! Puts the Corvette to shame (in the looks dept.)!!
In my personal opinion, the Corvette is a cheap looking sports car. But thats ME.
Keep in mind though, that the Corvette C6 is at the end of it's life cycle. It would suck to drop $50k on a car just for it to be old and outdated in a year or so. Versus the Camaro, which I would assume still has a few (3-6) premium years in it before a major re-design.
