Dude, this story is rediculous. I would be PISSED. I would have to notify FoMoCo, there is some kinda hotline, I'm sure the number is around here somewhere.
I would file a formal complaint with the dealer.
People these days don't care about anything if it's not theirs. They think if they just throw something together and it works, then it's good enough. Getting people to do good work is next to impossible today. No one takes pride in there work, just get it out the door, Next.
I'm going through the same thing on a house. Decided to buy a new house, look at one he was building, say I want it exactly like this, except a few minor changes. Basically he hires the subs and they do what they want, and the excuse I get is, I can't change it now, they have to go by code. Any DIY will know there is a big diff between, "by code" and a good job. Nothing really major, just irratating.
Sorry to hack part of your thread, I just had a minor vent.
