The headliner is considered an "irreversible interior component." If the edges are delaminated or there are deep, hard-to-clean dark water stains, it will directly lead to a downgrade in the interior grade, even if it does not affect driving. We will not use pins or low-quality glue for cosmetic repairs.

The method to deceive the dashboard warning light is to install a resistor. Our technicians will deeply read the real-time resistance values from the airbag control module (SRS Module) data stream and check for any non-factory stitching or adhesive marks on the steering wheel/passenger panel to uncover the disguise.

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.
