well i bought a 2000 X 4.4l, Ran like crazy... but all of a sudden in three days the tranny broke, engine has some problems (they told me it was repaired before) self level suspension and some other scary things happened... i am selling this one, selling it because i think fixing these problems are going to be too much money and energy. but for sure i am getting another X5... Great car. Just can't wait before they sell this one so i can hop onto another one. So check it wisely, if it doesn't have problems, GET IT. It's really worthed.
