I just passed this magic number on my 92YJ. I bought her new off the lot just over 12 years ago. Man, this Jeep's been good to me!
Still running original 4.0L engine and Ax-15 tranny. I've never had to do anything except routine maintenance, and it still runs great. She leaks a little oil, but big deal. Most everything else has been swapped out or modified though.
Just had to brag some :).
Terry.
