We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

To prevent intermittent failures due to aging of the resistance wire, we will start the engine and set the seat heating/ventilation to maximum for at least 5 minutes, confirming significant temperature changes or airflow output in the cushion and backrest using an infrared thermometer or body sensor.

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."
