For older vehicles or those used in high temperature and humidity areas, we will focus on opening the hood to check if the insulation of the wiring harness in the high-temperature area of the engine compartment is cracked or brittle, to identify potential short circuit risks that could lead to spontaneous combustion.

Yes, but it will be downgraded. For vehicles that are out of warranty and have no claims records, we will require a more in-depth physical inspection and clearly label the details page as "Data Unavailable" to ensure transparency about the risks. These vehicles typically have a higher price discount.

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.
