After paying off the car loan, the customer does not need any money to go to the vehicle management office to handle the unlending procedure. The details are as follows: 1. Relevant documents are required for unlending: the vehicle unlending itself is free. Customers only need to prepare their personal ID card, car driving license, driver's license, loan settlement certificate and vehicle registration certificate issued by the loan handling bank or automobile consumer finance company. 2. There is a service fee for entrusting an agent to handle the mortgage: The customer may not have time to handle the mortgage deposit in person, so he or she will entrust an agent to handle it. There are many 4S stores that provide agency release services. If the 4S store handles the release of the loan on your behalf, the 4S store may charge a certain service fee. 3. Report compulsory charges in a timely manner: If a 4S store imposes mandatory charges, customers can also call the local Banking Regulatory Commission or the industrial and commercial department to report the matter to safeguard their legitimate rights and interests.
