Section 13-211 - Terminal rental adjustment clause(a) In this section, "terminal rental adjustment clause" means a provision in a contract permitting or requiring the rental price of a motor vehicle or trailer to be adjusted either upward or downward by reference to the amount realized upon sale or other disposition of the motor vehicle or trailer.(b) Nothing in this section exempts a motor vehicle or trailer from the payment of any fees or taxes required at the time of titling a vehicle under the Maryland Vehicle Law.(c) Notwithstanding any other provision of law, in the case of a motor vehicle or trailer that is not leased, or used, primarily for personal, family, or household purposes, a transaction does not create a sale or security interest merely because the contract on which the transaction is based contains a terminal rental adjustment clause.
