N.M. Stat. § 66-3-401
Operation of vehicles under dealer plates.
A. Any vehicle that is required to be registered pursuant to the Motor Vehicle Code
[66-1-1 NMSA 1978] and that is included in the inventory of a dealer may be operated
or moved upon the highways for any purpose, provided that the vehicle display in the
manner prescribed in Section 66-3-18 NMSA 1978 a unique plate issued to the dealer
as provided in Section 66-3-402 NMSA 1978. This subsection shall not be construed as
limiting the use of temporary registration permits issued to dealers pursuant to Section
66-3-6 NMSA 1978. Each dealer plate shall be issued for a specific vehicle in a dealer's
inventory. If a dealer wishes to use the plate on a different vehicle, the dealer must
reregister that plate to the different vehicle.
B. The provisions of this section do not apply to work or service vehicles used by a
dealer. For the purposes of this subsection, "work or service vehicle" includes any
vehicle used substantially as a:
(1)
parts or delivery vehicle;
(2)
vehicle used to tow another vehicle;
(3)
courtesy shuttle; or
(4)
vehicle loaned to customers for their convenience.
C. Each vehicle included in a dealer's inventory required to be registered pursuant
to the provisions of Subsection A of this section must conform to the registration
provisions of the Motor Vehicle Code, but is not required to be titled pursuant to the
provisions of that code. When a vehicle is no longer included in a dealer's inventory,
and is not sold or leased to an unrelated entity, the dealer must title the vehicle and pay
the motor vehicle excise tax that would have been due when the vehicle was first
registered by the dealer.
D. In lieu of the use of dealer plates pursuant to this section, a dealer may register
and title a vehicle included in a dealer's inventory in the name of the dealer upon
payment of the registration fee applicable to that vehicle, but without payment of the
motor vehicle excise tax, provided the vehicle is subsequently sold or leased in the
ordinary course of business in a transaction subject to the motor vehicle excise tax or
the leased vehicle gross receipts tax.
