I bought one of my Jeeps from Portsmouth. only thing with going out of state is they cant do any of the registration stuff for you so you need to do all the leg work. I also used the Tread Lightly, make sure you negotiate trade value before you pull the Tread lightly card out as they might try and hose you when they find out they wont make as much off the jeep. End of the quarter is a great time to buy as they may have incentive to move inventory.... oh its end of quarter tomorrow. LOL

2012 Jeep JKU 2.5' Terafkex spring lift, Rock Hard Bumpa, skids, BodyArmor4x4 sliders..
There is a guy selling this JKU on ENH. Good price, lots of mods. I thought of this thread once I saw it. Not sure if it's what you are looking for but it might be worth taking a look.
Harr In Worcester was good experience. They sell your trade as they buy it and will offer you cash for it even if you don't buy. They claim to have a haggle free zone and sales people work on quota vs commission.
Jeep doesn't offer many incentives for JKs/JKU's because they are so popular and sell so well. My main selling point was finding a dealer that had what I wanted, and was willing to give me what I wanted for a trade in. I ended up going to rhode island for mine because they offered me the most for my trade.
