It takes a certain administrative cost on the part of GM to keep each dealer..plus the larger number of dealers increase the cost of coop advertising, training etc.
They are hoping the the remaining dealers will be larger and stronger, but product support could suffer.
We are selling our GMC 2500 diesel. Will switch to smaller mid size pickup. Or maybe a f150.
Buy a Tundra Oldexpat. It is made right here in San Antonio by non-union honest working San Antonians. There are also about 25 on-site suppliers that are run and operated largely by other non-union honest working San Antonians.
Buy Tundra. If you have never driven one, then go do it. It is the best truck made. Period. No, I am not an employee but I have been able to tour the plant during one of the open to the public days.
