Remote mechanical assessment relies on documented evidence: 1. Cold-start video: Ask for a video of the engine starting from cold — listen for rattles, watch for smoke (blue = oil burning, white = possible head gasket issue). 2. OBD scan: A full diagnostic scan reveals fault codes in the engine, gearbox, and electronics. Request the raw scan report, not a screenshot summary. 3. Service records: Cross-check mileage against maintenance records and inspection stickers; consistent records indicate a cared-for car. 4. Fluid check: Photos of the oil dipstick and coolant color tell a lot — milky oil or rusty coolant are red flags. 5. Test drive video: A short drive video shows gear shifts, braking, and steering behavior. Combine these with the pre-shipment inspection report. A seller who refuses to provide cold-start video or OBD data is a warning sign.

We use a calibrated high-precision paint thickness gauge to take multiple measurements on at least 13 metal surfaces of the entire vehicle. The original paint thickness of mainstream Chinese models typically ranges from 90μm to 150μm. If any area exceeds 200μm or even reaches over 500μm, we will directly conclude that the area has undergone bodywork and filler repair.

The V2L output standard for domestic models in China is 220V/50Hz. If your country's power grid standard is 110V/60Hz (like in some parts of North America), you cannot directly power local high-power appliances and will need an external transformer.
