I REALLY don't think the dealerships even allow the last item! You have to pay your invoice even before they call up for your car to be driven to the pick-up bay.

As far as the others? A lot of owners wouldn't be that specific...I know when my wife discovers a problem, she just wants it fixed...she doesn't care to do an autopsy or go through a week-long investigation searching for clues...that's what I'm there for. She figures I will take her car for a few days and eventually confirm what she had discovered...only with more detailed info...
