Well I have a 2004 and have been most pleased with the balance of power and handling. Took it to Willow Springs in 2006 (Spring Fling, Van Nuys Mopar Show) . . . was great on the road course. My buddy had his 2006 5.7 Hemi Charger . . . I was pulling away from him in all corners. Only spot it felt weak, was hitting the straight, could not get the speed up and the Charger would pull closer - but then the turns hit and I would pull away !!!

Course the best part was that I drove the car 3,300 miles round trip, hit the track, hit the car show and enjoyed it all ! Only spent $248 total on fuel too !!! All seems right in my books !
I would suggest, if you love the Crossfire, but want more Ummpfff . . .why not get an SRT6 ?? Aren't those supposed to be "The Bomb" ??? I would love one . . .but am most happy with my NA 6speed.
Cheers
Mark
