Come to Gilford, N.H. if you are looking for any exotic cars. We have, maybe this has changed in a year or 2, the largest stock of Vipers in the U.S. if not the world. He has Ferraris, M3's, Z06's.
Get the new SRT Ram. Just to say that you have it. and custom fab. a complete SQ system in it. There are plenty of performace parts for the Viper engine, you wouldn't have much of a problem bustin people up on the racetrack w/ one of those.
Edit: Oh yeah, and i forgot, it has one of them low tech engines that you are so fond of... Them pushrod engines like the ones found in Camaros, and older stangs.
