In December 2011, I purchased a used vehicle from a dealership for 11k cash. We are now in May 2012, and I still have not received the title / registration papers or the new plates. The vehicle was from out of the state, so the dealership was supposed to obtain new CA plates for the car. I went to the DMV, and the DMV stated that the vehicle is still listed in the dealership's name. When I call, they claimed that they mailed the registration to their headquarters, and it's the headquarters backlog that is delaying the submission of the DMV paperwork. I paid cash for this vehicle, so title should have been transferred immediately to me. The tags are going to expire in June. What are my legal options?
