I was a hater when it first came out, but I have actually been on the trail with them (Two and Four Door, Rubi and not Rubi). The only problems I've really seen with the four door is high-centering on some hills due to the long wheelbase. I was hard-core against the mini van motor in the new Jeep as I still firmly believe the H.O. 4.0 inline six to be one of the most durable and reliable motors ever, but the folks I know who actually own and drive them say that it works fine. I would agree that it's probably underpowered compared to the TJ, but the mileage is comparable. Also, the TJ is smaller than even the 2 door.
I like the styling as well. I might even consider buying one used someday. Lifting it is a piece of cake; all you need is a budget boost (2") and you can stuff 35s under there with no issues and it looks pretty sick.
Firebird67dude, if you really like the JK, you might want to talk to some folks who actually own one (Not the dealer; they'll tell you whatever you want to hear). Why not check out
www.northjerseyjeepclub.org? I know quite a few JK owners there who would give you an opinion.
