The car loan has been repaid, and the guarantee company can't find it. They have the owner's driving license and car invoice. What should I do if I want to sell my car?

The problem is not big, go to the dealer to make up the invoice; Does the owner's license refer to the motor vehicle registration certificate? If there is, I just need to take my ID card and driving license and drive to the vehicle management office where my ID card is located, and I can get it on the same day. By the way, check whether this car has been mortgaged at the vehicle management office. If there is, it will be a little troublesome. You need to take the loan contract to the court to sue the guarantee company, and then cancel the mortgage registration with the judgment and the notice of assistance in execution.
