What is the difference between an auto trade invoice and a 4S store invoice?

[SanBarrett]

There is essentially no difference between an auto trade invoice and a 4S store invoice; the only distinction lies in the issuing company. Below are the documents that car owners need to check when picking up their vehicle: 1. Purchase Invoice: The purchase invoice is not only required for vehicle registration but also for insurance, vehicle inspection, and transfer of ownership. It should be obtained when picking up the car and kept safe during use to avoid loss. 2. Vehicle Registration Certificate: Also known as the 'green book,' the vehicle registration certificate is generally not needed in daily use but is indispensable when transferring ownership. If the car is purchased with a loan, the green book is usually held by the bank or the 4S store. After the loan is fully repaid, it must be released and retrieved. 3. Warranty Service Card: The warranty service card covers free repairs for faults and damages caused by quality issues within a certain period or mileage, typically three years or 100,000 kilometers. 4. Vehicle Maintenance Manual: The vehicle maintenance manual should be carried with the car at all times. It serves as a reference for any uncertainties and helps avoid confusion when encountering car abnormalities.
