All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

Yes. The inspection report includes a specific "consumable parts consumption list." We will measure the tire tread depth (in millimeters) and the remaining brake pad thickness using calipers. If the tire tread is below the legal wear limit of 1.6mm, we will note it as "recommended to replace immediately upon arrival."

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.
