Massachusetts General Laws Part I. Administration of the Government (Ch. 1-182) Ch. 140, § 62

Every licensee shall keep a book on the licensed premises, in such form as shall be approved by the registrar, in which, at the time of the purchase, sale, exchange, or receipt for the purpose of sale, of any second hand motor vehicle or parts thereof, shall be legibly written in the English language an account and description of such motor vehicle or parts, with the name and address of the seller, of the purchaser, and of the alleged owner or other person from whom such motor vehicle or parts were purchased or received or to whom they were delivered, as the case may be. Such description, in the case of motor vehicles, shall also include the identifying number or numbers required by the registrar, and shall also include a statement that the identifying number or numbers have been removed, defaced, altered, changed, destroyed, obliterated or mutilated if such is the fact.

Notwithstanding the previous paragraph, a licensee licensed under sections 58 and 59 shall be in compliance with this section if the information required by the previous paragraph is recorded and maintained in the licensee's electronic data management system in a form and format approved by the registrar; provided, however, that the registrar shall not require the licensee to engage in duplicate recording and maintenance of the information for each vehicle. The registrar may require a licensee to: (i) make readily available a printout of a specifically requested used vehicle record for a vehicle that the licensee has acquired, sold or traded; and (ii) maintain or make readily available a printout of the used vehicle record of each vehicle that: (A) is on the licensee's premises on the date of the inspection; and (B) the licensee has acquired, sold or traded during the previous 7 days.
