Is the original invoice required when selling a used car?

[BeauDella]

Buying and selling used cars requires the original invoice. Here are the precautions for buying and selling used cars: 1. Check the driver's license: Check whether the patterns on the front and back pages of the driving license can match when combined, and check whether the photo and frame number on the driving license are consistent with the vehicle; 2. Check the vehicle insurance: Verify whether the frame number and engine number on the insurance policy are consistent with the driving license, and whether they are within the validity period; 3. Check the vehicle registration certificate: Check whether the font on the vehicle registration book is consistent with the driving license, whether the frame number and engine number are the same as the driving license, check whether the production date and registration date match the description of the car dealer, and check whether there are frequent transfers in the registration column within a short period of time.
