Tennessee Code Title 47. Commercial Instruments and Transactions § 47-2A-110

In the case of motor vehicles, semitrailers, or trailers, as defined in title 55, chapter 1, notwithstanding any other provision of law, a transaction does not create a sale or security interest merely because it provides that the rental price is permitted or required to be adjusted under the agreement either upward or downward by reference to the amount realized upon sale or other disposition of the motor vehicle, semitrailer, or trailer.
