Each dealer agent may collect a charge from the consumer to transmit electronically the registration and title data and the fees collected required to register a motor vehicle, issue a permit for registration, transfer a motor vehicle registration, or title a motor vehicle. This optional charge is in addition to other dealership fees or charges and the fees otherwise required to register a motor vehicle, issue a permit for registration, transfer a motor vehicle registration, or title a motor vehicle. The charge shall be separately stated and identified as “optional EVR charge” on the purchase agreement between the customer and the dealer agent and shall be disclosed on a separate document signed by the customer. If a customer declines to pay the optional electronic vehicle registration charge, the dealer agent is not required to register the vehicle, issue a permit for registration, title the vehicle, or collect the required fees.
