Brand New Vehicle damage at delivery

[Donutblue]

My 20 year old son and I went to a fairly new Chevy dealer in Westchester, NY last week and he purchased his first new Chevrolet, a 2006 Chevy Silverado, extended cab with all the Bells and Whistles. He had to wait a few days for the dealer to get the vehicle he wanted from a dealer in PA. After and agreed date (by both dealers) to pick up the vehicle in PA, they were turned back and told the owner had to be there to cut a check for the swap and come back the next day. The new truck was obtained the following day from the PA dealer. We went to pick up the truck this morning. I almost fell over looking at the rear passenger door to see it was a different color. Upon examination I could see overspray around the body edges, and dried compond all over the rear seat and rear interior frame. The salesman told me they just got the truck back last night from PA and this is the first he saw this damage. Needless to say, we killed the deal and temporarily ordered a 2007 (at the same agreed upon price). Besides a major bargaining chip is anyone aware of a mandatory reporting of body damage to a new vehicle. I mean this entire rear door (extended cab) was totally a different color and really should have been picked up by the driver that picked it up from the PA dealer. Needless to say the son is really bummed out, being his first new vehicle and no other vehicles available matching his criteria, ie: color and options. Suggestions open
