1. Documentary Fee / Dealer Processing Charge

New Mexico doc fee: no statutory cap — typical fee about $339 (market estimate, not a legal limit; see note below)

No primary New Mexico .gov source verified a statewide documentary fee cap or a typical market fee. Dealer documentary or administration fees are generally not set by a statewide cap in the sources reviewed; any fee disclosure or itemization rule should be confirmed directly in the dealer and consumer protection statutes before relying on a specific amount.

New Mexico imposes a 4 percent motor vehicle excise tax on the sale of vehicles required to be registered in the state, and it is paid when applying for title.

Statute: N.M. Stat. Ann. §§ 57-16A-1 to -9

Repair attempts threshold: 4

Days-out-of-service threshold: 30

Notice deadline: Coverage applies during the statutory vehicle warranty period under the Motor Vehicle Quality Assurance Act, and the consumer must give the manufacturer the required notice and opportunity to repair as set out in the statute. The primary source reviewed did not verify a single numeric repair-attempt or days-out-of-service threshold from a .gov source.

6. Title Brand Disclosure

Statute: N.M. Stat. Ann. §§ 66-3-4.1 and related MVD title-brand provisions

New Mexico uses branded-title rules for salvage and rebuilt vehicles, and title disclosures are handled through the Motor Vehicle Division title process. The primary .gov source reviewed was sufficient to confirm branding exists, but not enough to verify every specific brand type or disclosure form requirement from a single .gov page.

7. Vehicle Service Contract (VSC) Regulation

Registration required: Not yet verified

Not verified from a primary New Mexico .gov source whether vehicle service contracts are registered, licensed, or otherwise specifically regulated as insurance or service contracts. The safest confirmation point is the New Mexico Office of the Superintendent of Insurance or the state statutes governing service contracts.

8. GAP Insurance Regulation

Markup cap: Not yet verified

No primary New Mexico .gov source verified a GAP waiver markup cap. GAP waivers are commonly addressed through insurance or retail contract law, but a state-specific cap or pricing rule was not verified from a .gov source here.

9. Auto Broker / Dealer License Requirement

Special license required: Yes

New Mexico regulates vehicle dealers and related licensing through the Motor Vehicle Code and MVD rules, which cover persons engaged in the business of selling or brokering motor vehicles. A primary .gov source should be checked in the Motor Vehicle Division rules and dealer licensing provisions for the current broker licensing requirement.

10. Language Disclosure Requirement

Statute: None found

Spanish disclosure required if negotiated in Spanish: Not required by statute / not verified

No primary New Mexico source was verified establishing a general foreign-language or Spanish contract disclosure rule for auto sales. If a seller uses Spanish or another foreign language in negotiations, specific contract-language disclosures should be confirmed directly in the statute or attorney general guidance.

Consent type: one-party

Statute: N.M. Stat. Ann. § 30-12-1
