The technician will check the production date codes and brand logos in the lower left corner of all the car's glass (including the windshield, four doors, and rear window) to see if they match the vehicle's factory date on the nameplate. If any glass is found to have a date later than the vehicle's production date, it will be recorded as evidence of a "previous damage replacement."

Yes. For bulk purchases, we can organize and package the core historical records (transfer records, maintenance summaries) for each vehicle. If an English version is needed, we can provide a basic machine translation reference, and human translation assistance for key technical terms.

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.
