They're talking the '12 is supposed to have around 475-500 Horse but it hasn't been confirmed yet to my knowledge. All the older ones have the 425 HP 6.1L Hemi in them. They're not too difficult to find, not as common as the regular GC but they're out there. I haven't researched them in awhile but expect to pay mid 30's for an 07 with 25-35k miles.
