I have a 1997 Jeep Wrangler 4.0, that I use for hunting and locally. The 4.0 straight 6 engine is bullet proof. Simple and reliable should go well over 200,000 miles. So, I would look for an 06 or earlier with the straight 6, 4.0. They stopped making them in 07. They hold their value well and there is a cult following. Unless you are looking for something newer and more money.
