Yes, fewer than 1,000 SRT6 roadsters ever made. No collector market.

I got mine for $15K in December 2010 from a no-name dealer in Sacramento with 60K on the clock. Nobody on this forum remarked on its being advertised, though it was up for almost a month before I bought it. It has been my daily driver for 35K miles since, with the only out of the ordinary maintenance being the fan relay.

Am I lucky? Yes. Every used car is a pig in a poke, and don't forget even transferable extended warranties do not last forever. You will spend money on maintenance whether you buy that garage queen or not. Your greatest difficulty will be finding a reputable shop that knows how to work on your car.

Okay, your greatest difficulty will be learning how to drive it tamely and wiping the permagrin off your face when you don't. I wish you the best of luck in your search and after, and welcome to the community.
