I'm a jeep guy, too - have had two XJ's (First one went to 318K miles, and that included being totaled, front end, at 125K) - Still have the other one. (The first one is still on the road, too.)
Do not buy this Jeep - You can find another cheap xj very easily, without this problem.
The Samurai has a pathetic (but reliable) 4 cylinder engine, and it WILL roll over. The Jeep is a much better vehicle in many ways.
