Mrs. Mud's '94 YJ has 150+K and still going strong (clutch, brakes, exhaust - typical usual maintenance stuff replaced). My '03 TJ has only 38K, but from what I've read here, she's just broken in!!
97 TJ 2.5 112,000....still ticking strong...have been through 2 cats though.
changed the serp belt for the first time at 99,000....wanted to see how long it would go, but got afeared of it!
