I'd look for a 12+ with the Pentastar. The 3.8 was gutless and you got the 42RLE tranny which isn't great. RWD based Jeeps are the good ones, it's the FWD ones that suck. My Liberty has 224k miles and runs great. I've had two Jeeps with the 4.0 and I honestly love the 3.6 with the 8 speed trans a little more.
