^right on. 5 grand is a lot for a yj, especially with that mileage. i'd go 92, and talk them down a little to.
make sure when looking at yj's check these key rust areas, lift carpet and look at front floor boards, rocker panels in and out. rear of frame, and windshield frame, and rear body mounts. its bound to have some rust, but make sure its not rotted through
