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).

Europe and some developed countries have very strict regulations on greenhouse gases. If required by customs, we will specify the exact refrigerant type and charge amount according to the vehicle's air conditioning compressor nameplate in the remarks section of the packing list and commercial invoice.

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."
