I've owned this BMW for about 5 yrs. I have 71k on it and nothing has gone wrong so far thank GOD. A lot of people complain about many different things but I think the problem is on how fully loaded you get it. There is a saying " If you go German, then you go all the way". I believe this because I've purchased only BMW my whole life and each time its been "FULLY LOADED" This means Sport, Premium, Winter package, and every other bell and whistle that goes with it. Try it, I did, and I love it....
Bought this X5 4.4 used, with 28K mi. and the Dinan package (throttle body, exhaust, 19" rims, etc) from an AZ reseller. Whoever traded this truck in was nuts! This one's for keeps. Performance is BMW-esque, suspension firm, but not harsh, and handling outshines most sports cars. And the Dinan package puts it in a league of its own. A note of caution: max out on an extended warranty. It will pay for itself. They just don't make 'em like they used to. Speaker grilles fall off, cup holders fail to close, electronic gremlins that you just learn to live with. If you live in good terrain where the roads are long, you'll love it for all the right reasons.
Get that non-ergonomic (but great sounding) radio and other electronics (like PDC) to be more reliable. I get frustrated in having to bring the vehicle in for such minor repairs. And why does every part have to be dealer- bought? My wipers don't perform right unless I purchase BMW blades!
The X5 is, by far, the best vehicle I have ever owned. It still turns heads, runs like a top, and corners like it's on rails. The only thing I can say that's bad about this vehicle is that the user interface on the navigation system is atrocious, and the CD changer is in the cargo area. If I'm picking nits to this degree, you can see that I'm grasping at straws. I wind up negotiating with my S.O. about who gets to drive it.
Fast, solid, comfortable, spacious, agile, hot looks.
Rob the nav system from Land Rover's LR3. Typical european brakes require frequent wheel cleaning due to brake dust.
I have had an excellent experience owning my third BMW. The X5 has been great in performance as a sports SUV as well as a work horse SUV. I consistantly tow a 3800lb boat and drive in the rockies. The 3.0L has been reliable and trouble free. It had a few recalls in '02 but they were fixed quickly. Over all a 9.5 out of ten.
