Is MBFS able to complete requests to transfer vehicles to third parties at this time?
Department of Motor Vehicles (DMV) office closures throughout the country have impacted the transfer of title and registration process. As a result, we are unable to accept vehicle transfer requests until further notice. Vehicle transfers already in progress will be completed and both parties will receive a confirmation package from Mercedes-Benz Financial Services when the transfer is complete.
