Vehicle inspection, engine number tracing, license plate removal, photography → Traffic violation inquiry and handling → Payment of transfer fee → Transfer registration → Receipt of receipt form → Collection of vehicle license and registration certificate. Ensure the legal compliance of the vehicle's documents, check the vehicle's documents, registration certificate, vehicle license, and then compare the chassis number and engine number. Start the engine to listen for any abnormal sounds, fully depress the accelerator pedal and then suddenly release it to observe if there is any shaking. Inspect the most hidden parts of the vehicle. If inconsistencies are found, it may indicate that the vehicle has undergone major repairs or significant accident repairs or replacements.
