Never thought I'd see the day when I'd be a Mopar guy too but I ended up buying a 2011 Challenger SRT8 Inaugural Edition with the 392 (6.4L) and 6-sp Tremec. Just bought it on Friday through a friend of a friend who I think had to sell it because of a divorce. It has only 19,000 kilometres (about 11,400 miles). HP and torque are both rated at about 475.
Got it in storage right now, waiting for spring!
