I've had the normal run through window regulators, CV boots, FSR and the door handle carrier. The only major shock was the front driveshaft and a transfer case at 136,000 miles for $4200. But I don't hesitate to drive for 1000 miles non-stop or tow a PWC for 600 miles with the X5.

With 243,600 miles on it, the only thing that actually shows any wear is the leather on the driver's seat and some cloudy headlight covers!
