Thank you for the additional information.
I am sorry to hear of your dilemma. I realize how frustrating this is for you, but I believe I have information which you will find helpful.
If the title was never received from the dealer or seller, you can file an application with the DMV for a duplicate or paperless title using the Bill of Sale from the seller.
The following link as the form: http://www.dmv.ca.gov/forms/reg/reg227.pdf
The form is self explanatory, but you may need the seller's cooperation.
If they refuse to cooperate, you are going to need to sue them for breach of the sale contract.
It is my privilege to assist you. Let me know if you need further information. I hope I have helped you beyond your expectations in the service I have provided to you. I am here for you.
