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.

It depends on the brand, so verify before buying: 1. OTA updates: most newer Chinese EVs update over the air, but some brands tie updates to the region of registration—an exported car may stop receiving them or stay on China firmware. 2. Companion apps: functions like remote climate, charging status, and location often require a Chinese phone number or mainland server access; abroad they may work partially or not at all. 3. Language and units: check the infotainment can switch to your language and your units (miles/km). Ask the exporter to demonstrate the app functions live on video before purchase, and get written confirmation of what will work after export. For the battery, request an SOH (state of health) report—battery replacement is far costlier than any software limitation.

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.
