I'm thinking of purchasing a 2004 or 2005 BMW X5 4.4, Sport package edition on either year and both that I'm looking at have high mileage, around 90K. Are there any major problems that I need to know about before I make a decision? If I got this vehicle, I would probably driving it until it hit around 130K. I heard BMW are more dependable than most when they hit over 100K. I thank you for any remarks and comments in helping me make my decision.
