N.M. Code R. § 12.2.4.21
Dealer price advertising:
A. It is an unfair or deceptive trade practice for a dealer to advertise the price of a new motor vehicle unless the advertised price is the full cash price for which the dealer will sell the vehicle. The only charges that may be excluded from the advertised price are:
(1) federal and state taxes;
(2) license fees;
(3) vehicle registration; and
(4) dealer transfer service fees, if the advertisement clearly and conspicuously discloses, in close proximity to the advertised price, the amount of any such fee and that the fee is a dealer imposed fee; provided, however, that it is an unfair or deceptive trade practice for a dealer to fail to disclose in writing to a buyer purchasing a vehicle on which no security interest is retained that the buyer may register the vehicle on his own without paying a dealer transfer service fee.
E. It is an unfair or deceptive trade practice for a dealer to use an illustration of a motor vehicle in an advertisement unless the illustration is that of the motor vehicle advertised. If an illustration of the advertised vehicle is not available, then the dealer must clearly and conspicuously disclose that the illustration is not the vehicle being advertised.
