The value of parts, motor oils and similar items taken from inventory held for sale, or purchased under Type 2 (resale) NTTCs, by automobile dealers for use in repairing or maintaining vehicles used by the dealers in the operation of the dealerships, as distinguished from vehicles held for sale, is subject to compensating tax. A new vehicle which has been titled and registered, other than pursuant to Subsection C of Section 66-3-118 NMSA 1978 pertaining to new vehicles held for sale and allowed to be registered without payment of the motor vehicle excise tax, will be treated as a vehicle used in the dealer's business for purposes of applying Section 3.2.10.18 NMAC.
