im new here! ive searched the archives for as much as i could find on the strengths/weakness of different models/years. i have an opportunity to pick up a meticulously maintained 2000 XJ for 4k. it has 100k miles and is in pristine shape. i know the seller and know that all scheduled maintenance has been completed. my only concern is that he had to have the front differential rebuilt at 97k. ever since he had the differential rebuilt, he says that occasionally the dash light won't come on when going into 4WD. he does very little offroad, but did do some towing with it. maybe towed 2k lbs for 5k miles. recently, after having his oil changed, he was told his AT fluid was really messy, even though it had been flushed 5k miles prior. i certainly don't trust those lube places, but it freaked him out. i plan on using it mostly for driving in the snow and on forest service roads...mild 4x4 use and it won't be a daily driver, maybe 3-5k miles per year. i was hoping for some insight on what problems i may be getting myself into with this. BTW its the 4.0L I6 with AT. many thanks and looking forward to working on these rigs!
