I have a 2000 M5 with ~42,000 miles on it.
Few problems so far, just the usual oil consumption, a failed MAF sensor, a failed fan speed control and lately the flakey OBD display.
I would be happy to drive this for another 42,000 miles, but I am worried about what might happen when the warranty expires. The power train has so many highly engineered systems that were first-of-their-kind, I don't see much chance of 100,000 miles of trouble-free operation.
Am I just being paranoid? Does anyone have experience with higher mileaage E39 M5's? How about the boys in Europe, where this car has been around a while longer?
