Thanks for the info. I've been seeing references to the SRT-6 But really don't know anything about them other than it appears they were assembled by AMG with a different engine. Is there some exterior badging that would designate the car? To be honest, we hadn't given the Crossfire much thought until we drove one yesterday and was amazed by how well the car drove. We are looking for a retirement toy that is unique and something that we both can enjoy.
