Many car owners do not have their first maintenance done at authorized dealerships, leading to gaps in early data. In such cases, we do not blindly trust the odometer; instead, we analyze the tire production dates and wear levels, as well as the depth of grooves on the brake disc edges, using the "gold standard" of physical wear to infer the intensity of early use.

We will directly check the registration certificate (the big green book) and count the number of changes.

Apply for a certificate of origin from the local customs or trade promotion agency, proving that the country of manufacture is China. This is a necessary document for customs clearance in regions like the Middle East and Southeast Asia.
