Def would consider a Cherokee.
if you are concerned about rust check the frame rails and rockers. As check the pass side floor to see if its wet. Body thats the only things to look for.
Engine wise 00 and 01 models had a weaker head the 0331 heads. Only other common thing is the Crank position sensor tend to go after 100k ( $70 part ).
My jeep has the 4-speed AW-4 automatic and is a tank has self adjusting bands and if maintained will last as long as the engine from what I have seen.
The only real issue you will see with most is sagging suspensions to replace everything runs just over $500. Or you can put a small 3.5" lift on it for about the same or a little less.
thing I would look into updating if you bought one. Headlights the stock one flat out suck. they sell a upgraded wiring harness and a set of e code H4 headlights for $100ish.
IF you want I can let you check my Jeep to see if it fits you needs.
