Well, I guess this dealer won't ever trust the MoCo rep again...and he rightfully shouldn't. If he had no intention of issuing the authorization for new parts, he should never have said so.
I don't know how much clout dealers have with the MoCo--probably very little, but as I read this story, I'd have to set up a meeting with me, that Rep. and someone higher up to get them to "clarify" their policies with respect to their expectations of dealerships and relations with MoCo reps and customers.
If that rep has half a brain, he certainly understands the blow he has dealt to the dealer and you (the customer). I'd like to ask him if that's the way the MOCo wants to do business?
My personal footnote about factory "reps". I once had a Nissan truck that had a clunk in the rear end. After much haggling with the dealership service manager, he agreed to call in the regional factory "rep" from out of town. About a week later, after he allegedly looked the truck over, I met the guy, who agreed to pull the rear inspection cover off the differential to look at the gear set. I had to point out to him that this truck had no bolt-on inspection cover, it was a welded third member type assembly that dropped out as a unit from the front. He just stared at me. The point is that the factory "rep" didn't know much about the product. I mean all he had to do was bend over and look underneath. I asked him if he had looked--another blank stare. Later, when I was back at the dealer, I saw the same guy working the floor as a salesman. He saw me and ducked into the back somewhere.
He was no factory rep at all--just a salesman playing the role to get rid of me. Needless to say, I never went back to that dealer. But they don't care--plenty more customers where I came from.
Anyway, whenever somebody starts talking about factory reps, I remain unimpressed.
