The main down side to any of the Cherokee's was electrical wiring. They didnt have a great track record.

But thats not to say they are junk. But if you can find one with fewer power options you may save some gremlin chasing in the future.

Also the XJ's were prone to rust, but in the price range you are looking, that shouldn't be as much of an issue.

the 4 cylinder was nearly bullet proof, and they are a very capable line. Numerous aftermarket goodies for them as well.
