Hey Kevin, I recently purchased a 1995 XJ Cherokee for my daily driver.
It's great, these have galvanized underbodies so rust isn't an issue down there.
If you can get your hands on some service history to see if the Jeep has been cared for, that may help, at least offer peace of mind. These things run for ever, I have 114,00km on the clock (70,00 miles) no problems at all runs and drives strong and is surprisingly comfy, no sway or tilt around corners. I'm getting a 2" lift soon with some 31" tyres to add some "chunk" to it. Had the windows tinted to 5% after these photos were taken.

Good luck and keep us posted.
