Why don't you have an invoice and a motor vehicle driving license when you buy a car in 4s?

To buy a car in a 4s shop, the 4s shop must give the customer a car purchase invoice and a motor vehicle registration certificate. If not, you can complain to the administrative department for industry and commerce about the 4s shop. In fact, you really don't have to complain. Just tell them that you don't give the invoice and motor vehicle registration certificate. Just go to the administrative department for industry and commerce and complain, and they will give you the invoice and motor vehicle registration certificate. Otherwise, if you really complain to them, they will face a huge fine.
