A contract, entered into in this State, which transfers the right of possession for use of a vehicle by a natural person primarily for personal, family, or household purposes, for a period of more than one year, for a total contractual obligation not exceeding $25,000, whether or not the lessee has the option to purchase or otherwise become the owner of the vehicle at the expiration of the consumer lease. The term consumer lease does not include the following: an agreement which meets the definition of a credit sale in Regulation Z, 12 C.F.R. § 226.2(a) or a retail installment transaction as defined by the Motor Vehicle Retail Installment Sales Act, or a lease for agricultural, business, or commercial purposes or one made to an organization. A consumer lease may include the purchase of goods, services, or benefits incidental to the lease, whether or not the purchase price is included in the capitalized cost. Unless expressly provided in the contract, a contract that substantially complies with this Act does not create a security interest in a vehicle as the term “security interest” is defined in subsection 37 of § 1-201 of the Uniform Commercial Code. For the purpose of this definition, “total contractual obligation” is computed on the assumption that the consumer lease is not terminated before the end of the scheduled term, that there is no default, and that the lessee does not exercise any purchase option. “Total contractual obligation” includes the capitalized cost reduction; plus the scheduled lease payments over the term of the lease, or in the case of a single payment lease, the single lease payment; plus any disposition fee or other disposition charges known or calculable at the time the lease is executed.
