N.M. Code R. § 12.2.4.12
Below market finance charge:
B. It is an unfair or deceptive trade practice for a dealer to advertise below market financing rates unless the advertisement clearly and conspicuously discloses all the terms which must be met in order to qualify for that advertised rate. Examples are large down payments, hidden finance charges, unusual terms of the loan or higher selling prices.
