Chris, something is not right! Your dealer received your car, not a demo or .... but YOUR car that you ordered months ago. I think that the dealer has no right to keep it back because he don't have another car to show. Indeed it is Chryslers problem but why do you have to deal with it?
I understand you want to keep a good relation with your dealer. Still you pay (alot) so you must be demanding not the dealer.
I hope you have it soon!
