The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

Completely different. The assessment of commercial vehicles focuses on: the extent of wear/deformation in the cargo area, whether the frame has been twisted due to overload, the fatigue of the leaf springs, and the emissions of the diesel engine. Minor exterior scratches carry very little weight in the assessment of commercial vehicles.

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."
