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.

A realistic timeline: sourcing and negotiation 3-7 days; deposit and booking 1-2 days; pre-shipment inspection 2-4 days; export clearance and vessel booking 7-14 days; sea freight 2-5 weeks depending on destination; import customs clearance and port release 5-10 days. Overall, plan for roughly 5-8 weeks from order to port of destination by sea. For Central Asia and Russia by rail, 2-3 weeks total is common. Tips: ask the exporter for a written schedule with milestones (inspection done, customs cleared, vessel loaded, ETA); track the vessel yourself once you have the container or booking number; and remember Chinese holidays — Chinese New Year and Golden Week can add 1-2 weeks of delay.

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.
