Had to replace U-joint, rear and front brakes, O2 sensor, throttle sensor, a battery and an alternator.
There is more, but that is all that I can think of. Oh yeah, I had to cut out rust.
I had a soft top, it was miserable. It was a pain to put on and off. It would always come unvelcroved or zipped.
I liked driving it. The manual was a lot of fun at first. The steering was very quick to respond because of the short wheel-base.
It wasn't very good on gas, but it would have been worse.
It got wet with the top on all the time, whenever it rained. I hated that.
The u joint thing would be your fault though, because the u joints have a port to lube them up. That's general maintenance.
The other stuff is stuff that's gonna fail over time that's not Jeep's fault.
