I am not an attorney, however, I would argue this dealership is in violation of the Federal Automobile Information Disclosure Act (a.k.a. Monroney Act).
15 U.S.C. §§ 1231-1233 (http://caselaw.lp.findlaw.com/caseco...tion_1232.html)

The Act states the manufacture’s sticker must reflect the destination charge that was paid by the dealer. This amount is to be included in the sale price of the vehicle. The reason for this requirement is so the consumer is well aware of the cost the dealer paid to have the vehicle delivered. It would seem to me, and again I am not an attorney, your dealer violated this law by charging you an amount that was greater then the true cost they paid, based on the information on your sticker.

If you wanted you could always file a complaint with the Federal Trade Commission, they are the ones who investigate such deceptive practices. To be honest, I would just contact Chrysler, as I am sure they will take care of this issue for you. Car manufactures rely heavily on brand loyalty and referrals. I believe Chrysler is not going to want to let this dealer continue using their deceptive practices, especially when it seems they are in violation of Federal Law.
Best of Luck!
