2. Regular brokerage company
3. Sign a formal transaction contract (the seal of the contract must be consistent with the name of the brokerage company corresponding to the car purchase). If the car condition does not match the dealer's description, you can go to the used car market to claim compensation. According to the regulations, the market has to return the car at the original price, and some markets even pay double compensation. Before buying a car, I suggest you go to First Car Network (www.iautos.cn), the largest used car website in China, to see the market and models of used cars. The used car information on it is very rich.
