Go to collinsbrosjeep.com they sell used jeeps in texas. they have a great list of jeeps for sale.
I own a TJ 1998. It has 105,000 miles on it. I had thought of selling it a few years ago and could not do it. I love my jeep. It's reliable. Always starts unless I leave the lights on.
Jeeps are great for most climates. I've heard of army guys really liking jeeps. What part of the country are you in? Off road is really fun if you are in places where you an take it off the paved roads.
PROS: Jeeps are fun to drive, and cool looking
CONS: They are not very reliable, uncomfortable on long drives, get crummy gas milage, are drafty, and flip over easily. They are also expensive to buy and insure.
