It starts well before service. In 2001, I wanted to buy a 2002 GMC Truck. I worked for a supplier to GM, so I was entitled to a "supplier discount." I went to Duplessis Pontiac-GMC on the way to work with a print out from the GMC website where I "built" the truck. I wanted the drive it off of the lot price. After being passed around from manager to manager, I was told "That price comes out of Flint, and we can't get it." OK, so I went to Capitol GMC a few days later and spoke to the sales manager for the same thing. Twenty minutes later, I had the price. The older I get, the less patience I have for the ol' run around and the BS it encompasses.
