2001 BMW X5 SUV 3.0i AWD 4dr SUV (3.0L 6cyl 5M)
Fun to drive? Yes; Plenty of Problems? YES
 Bought this car new in 2001. Put about 25K miles a year on it, 50/50 highway/local. Great car to drive! BUT nothing but problems - windows stick; doors freeze in cold weather, try driving with your left hand holding the door closed because it won't lock, or try getting in on the passenger side and climbing over into the driver's seat. Then there's the engine - twice in very cold weather something went wrong with the oil exchanger/valve? Car makes loud noise then plumes of black smoke emerge from the exhaust, dash & front grille. The first time BMW took care of it out of warranty - this time we're waiting to hear. Should be a recall item.
