Yeah, I don't know. With an 05 you'll probably be way upside down in it. I would just work on keeping your current one for a spell, and not worry about the new model for a few years. The second you roll 'em off the lot you lose thousands. I would at least give jeep tales a heads up to see if he can give you the skinny on trade in versus what the dealers would try to stick you for. You might even be better trading on an 05 rubicon unlimited, because of the new model, you may get a better deal.
