I have an E39 530d, wicked car. Taken mine from 141k to 175 in just over a year. Few faults but nothing really mega, wheel bearing, heater resistor pack & that's about it really. Autos are heavy on brakes IMHO, but it's nearly 2 tons of car with no engine braking.
Love mine, wicked motorway tool, I do 500 miles a week just to work, I'm averaging 39.7 mpg, and that's doing 85-90 most if the time.
