In the mean time, it is worth your while to post the names of the dealers. They don't care about you (after the sale) but they care about the word getting out and cutting into business. And not just here but in the Dealership Review section of the forums.
And take the car to another dealer even if you have to drive to the next town. You probably don't want those clowns working on your car anyway. Its been my experience of 40+ years of new car buying that the single most likely cause of this kind of behavior is sloppy work and bad decisions that gets warranty claims kicked back to them. And rather than fix themselves, they stop doing anything that isn't completely mundane.
