I've got a 1994 YJ with the 2.5 liter engine and a manual transmission. It's an "S" model. No lift. 15 inch radius tires.
My Jeep currently has about 156,000 miles. It runs wonderfully. I bought it from the original owner a little over 2 years ago. I have all the repair receipts for the vehicle. All the work done on it I would consider to be normal preventive maintenance. Brake pads, Brake shoes, rotors, spark plugs, fluid changes. The engine, transmission, and transfer case are all original. No problems. Never failed to start. Nothing has ever left me stranded.
I did have to replace a non-functional turn signal lever. The most difficult job I ever had to do was replace a broken exhaust manifold stud. These problems do happen when you drive around a 13 year old vehicle, but they sure won't leave you stranded someplace.
