I bought a 2002 E53 X5 4.4i for about half the book value as it had a list of faults as long as your arm. Read through this forum, Buy the parts from ebay or from scrap dealers and do the work yourself. I am not a mechanic but have learned a lot about my ride from this forum and so far I have fixed almost all of the faults myself. Buy a good code reader so that you know what faults you have and the guys on here will advise you on how to fix them. I love my X now and it has been a great deal of fun fixing the problems and learning about the car.
