The registration certificate will show whether the previous owner was an individual (registered with ID) or a company (registered with a business license). Vehicles under a company may be driven by multiple people, so we will focus on checking the uniformity of interior wear and the condition of the chassis.

We repeatedly confirm and emphasize to buyers before sale: after leaving mainland China, most Chinese smart electric vehicle ecosystems (such as cloud voice assistants, online maps, OTA updates) will be permanently offline. You are purchasing a hardware platform with excellent mechanical quality and a three-electric system; please use it as a "standalone" vehicle. Do not trust false promises from other channels claiming "perfect overseas unlocking and continuous official OTA updates."

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
