I had a 95 zj that had 390k when I traded it in, back in 09. Still got 4500 from dealer!! Rebuilt the transmission at 250k. Not the jeeps fault though. Previous owner was using it to tow their 38' boat around the hill country for a couple years and tore up 2nd gear. Had it serviced and the shop reconnected the transmission heat exchanger incorrectly. Hose popped off while I was pulling out of my driveway and I didn't know for about 5 miles. I found out it popped off in my driveway by following the trail all the way home. Looked like someone had been murdered an drug under my car. Found a great sport tuning shop that rebuilt it for cheap. Was getting 23 mpg out of it when I traded it in.
When people ask why I love jeep so much intel them about my ok zj. That thing was tonka tough. I really miss the old IL6.
