My 2001 Cherokee, with auto transmission, and in-line 6 cyl has 154,000 miles on it with no problems except for the crank sensor having to be replaced about 25,000 miles ago. It does not use any oil between changes (3000 miles), has no oil leaks and the auto transmission and transfer case have performed perfectly, it has never had any issues other than the crank sensor going bad and having a steering stalilzer wear out.
I am not sure why Jeeps get so much bad press, I use mine for gravel roads and light off-road use and have no problem going where I want,but I do not use it for rock-climbing or bashing it around like you see the folks in Moab doing.
If you find one be prepared to pay more than you may expect for a nice one and avoid the beat up ones that have been rode hard and put away wet.
