Okla. Admin. Code § 465:15-3-6
The suggested retail price of a new motor vehicle when advertised by a manufacturer, distributor shall include all costs and charges for the vehicle advertised, except that destination and dealer preparation charges, and state and local taxes, title, and license fees may be excluded from such price, provided that the advertisement conspicuously states that such costs and charges are excluded. However, with respect to advertisements placed with local media in Oklahoma by a manufacturer, distributor, or advertising association which include the names of the local dealers for the vehicles advertised, if the price of a vehicle is stated in the advertisement, such price must include all costs and charges for the vehicle advertised, including destination and dealer preparation charges and may exclude only state and local taxes, license, and title fees. MSRP is an exact price and may not be inflated arbitrarily, or otherwise misrepresented by a manufacturer, distributor or dealer.
