1998 Range Rover?

I have found a 1998 Range Rover with 20k miles under what it is supposed to have, according to KBB. It is in pristine condition from what I can tell, and has been well-maintained. I know that they have better reliability than the discoveries, but what other MAJOR problems are they notorious for, keep in mind this one has been better taken care of than most, and doesnt have a very bad history. Also I know that Range Rovers only start to become problems after 120,000 miles or so, with engine problems...are they notorious for major breakdowns before then?
