I am thinking about buying a new Jeep Wrangler as a retirement gift to myself. However, with gas prices the way they are, the fuel efficiency ratings discourage me. Is Jeep doing anything to improve milage in the newer models? Also, will Jeep bring back the 2 door Unlimited model like they had in 2006? I am not sold on or need a four door, but I like the extended wheel base of the Unlimited for hauling more stuff around. What I would really be interested is if the designers would consider bringing back the Commanche pick up truck.
