Any motor vehicle, trailer or similar conveyance used to transport another motor vehicle or crushed motor vehicle sold in violation of Section 63-21-39 or otherwise used to aid in the commission of a violation of Section 63-21-39 may be seized by a law enforcement agency and is subject to forfeiture ordered by the court in the manner and under the terms and conditions set out for forfeitures of a vehicle, trailer or similar conveyance in this article; however, no conveyance is subject to forfeiture under this article by reason of any act or omission proved by the owner thereof to have been committed or omitted without his knowledge or consent. If the seizing law enforcement agency has reason to believe that the conveyance is a leased or rented conveyance, then the seizing law enforcement agency shall notify the owner of the conveyance as soon as practicable after the seizure. A forfeiture of a conveyance encumbered by a bona fide security interest is subject to the interest of the secured party if he neither had knowledge of nor consented to the act or omission.
