A friend of mine at work has a 1989 Cherokee Limited for sale. It's a 4.0L with an automatic and 160,000 miles. It's in pretty good shape. No body damage, just faded paint. The only problem seems to be the transfer case. It won't go into 4wd, but it will run in 2wd. He's asking $800 for it. Do you think it's worth it?
