Not just crap service but, what really gets my goat, uninterested service. You take what the dealer says, like you say, in good faith, but time and time again they prove they don't know their arse from elbow. Shame because the good ones get tarnished with the same brush.
Just identified a problem with the X3 (still under warranty) and am now nervous about taking it to the dealer because of the lack of trust in what they say; crazy.
