I personally felt guilty about firing up the CTSV just to drive a couple miles to work, but it was nice having a big four-door when folks needed to go somewhere. As such, I don't much care for the Challenger. It's cool, no doubt, but it's cool from afar and not something I'd want around. Plus I have inherent distrust for Chrysler products. I might go in for a Charger SRT because it at least offers 4-door practicality to go with the nutty motor, but not a Challenger.
If you're interested in this general type of product, I think you should go find a Panther Marauder to match the SVT.
