N.J. Stat. § 39:10-21
All dealers for both new and used motor vehicles in this State shall have a certificate of origin, certificate of ownership, or writing provided in R.S. 39:10-6 for all motor vehicles in their possession. The director, either personally or by his agent, may demand production of, and examine, the certificate of origin, certificate of ownership, or writing provided in R.S. 39:10-6 for any motor vehicle in a dealer's possession, and examine and inspect any motor vehicle in his possession.
If the demand is not complied with, or there is no certificate of origin, certificate of ownership or writing provided in R.S. 39:10-6 for a motor vehicle in the possession of a dealer, or if it is not in conformity with this chapter, the director or his agent may seize and take possession of the motor vehicle, and hold it until the certificate of origin, certificate of ownership or writing provided in R.S. 39:10-6 is produced or is corrected, if defective, or ownership of the motor vehicle is established according to law. After the expiration of 90 days from the date the motor vehicle came into his possession, the director may sell it at public sale, upon at least 10 days' written notice of sale to the dealer, served personally or by registered mail, addressed to the dealer at his last known place of business, and notice of the sale being published for a space of two weeks, once a week, making three insertions in all, in one or more newspapers published and circulating in the county where the dealer has his established place of business and also by posting the notice in five public places in the county. The newspapers and places of posting shall be designated by the director. Upon the sale of the motor vehicle, all valid liens and claims for interest therein, if any, shall be transferred from the vehicle to the proceeds of sale, which, subject thereto, shall become the sole property of the State, to be used as other moneys received by the director.
