I have heard different versions about the reliability of X5 E53 and understand it should vary from case to case due to individual care of cars and other factors.

but in general, for 2004 3.0 Diesel sport Auto with 70,000 km on clock, with good care, how long should I expect to keep it until maintain/repair bill and breaking down start destroying the fun of having it? I still have 2 years 10 month factory warranty on the car.
