A person keeping a garage, hangar or place for the storage, maintenance, keeping or repair of motor vehicles as defined by the vehicle and traffic law, or of motor boats as defined by article seven of the navigation law, or of aircraft as defined by article fourteen of the general business law, and who in connection therewith tows, stores, maintains, keeps or repairs any motor vehicle, motor boat, or aircraft or furnishes gasoline or other supplies therefor at the request or with the consent of the owner or, subject to the provisions of subdivision two of this section, tows and stores any motor vehicle at the request of a law enforcement officer authorized to remove such motor vehicle, whether or not such motor vehicle, motor boat or aircraft is subject to a security interest, has a lien upon such motor vehicle, motor boat or aircraft for the sum due for such towing, storing, maintaining, keeping or repairing of such motor vehicle, motor boat or aircraft or for furnishing gasoline or other supplies therefor and may detain such motor vehicle, motor boat or aircraft at any time it may be lawfully in his possession until such sum is paid, except that if the lienor, subsequent to thirty days from the accrual of such lien, allows the motor vehicle, motor boat or aircraft out of his actual possession the lien provided for in this section shall thereupon become void as against all security interests, whether or not perfected, in such motor vehicles, motor boat or aircraft and executed prior to the accrual of such lien, notwithstanding possession of such motor vehicle, motor boat or aircraft is thereafter acquired by such lienor.
