Interior assessment is divided into three core areas: the driver's high-frequency contact area (steering wheel, gear shift, edge of the driver's seat), central control button area, and rear seats and ceiling. The natural sheen of leather surfaces (patina) is normal; however, any physical damage (such as leather tearing, fabric burn holes, or plastic breakage) will be classified as "structural interior damage" and clearly marked.

We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.

Yes. We will use a professional diagnostic tool to scan all vehicle systems, including the Engine Control Unit (ECU), Transmission Control Module (TCM), Anti-lock Braking System (ABS), and Airbag Module (SRS), and provide English screenshots of all current and historical Diagnostic Trouble Codes (DTCs).
