Obviouisly biasted towards Xfire here but.... No doubt you will have to pay a premium to get the camaro and then if you wanted to sell it within a few years you'd take some heavy depreciation. The SRTs have already been hit with depreciation and if you wanted to sell one you probably wouldn't loose much.

Of course the Camaro seats 4 - I think.

... you might consider a SRT6 Roadster ;-)
