I will have to agree. The driver thing probably comes in a big here as I've noticed that I take it a bit slower with this six speed. It terms of acceleration, I do think the Mustang has it just a little bit. Weight is a big killer of that displacement. As for everything else, I love the Challenger over the Stang. It just seems more comfortable, more room, better handeling. Overall I love the Challenger over the Mustang, but if the R/T had the 6.1L like the concept, it would have been a little more fun if you will, and more expensive.
