The "usage type" section on the vehicle registration certificate has legal validity. Any vehicle that changes from "commercial" to "non-commercial" has a usage intensity far exceeding that of personal vehicles, and we will label these prominently. Such vehicles are usually cheaper but have more severe mechanical wear.

A structured live video inspection can catch most mechanical problems. Ask the seller to do the following in order: Cold start: film the engine bay before starting — check for leaks, cracked hoses, and corrosion. Then start from cold and listen for rattling or knocking during the first minute; abnormal noises on cold start often mean worn internals. Fluids: pull the oil dipstick — milky or foamy oil suggests head gasket issues. Check coolant color and level. Transmission: with the car warmed up, film each gear shift, forward and reverse. Hesitation, harsh jerks, or slipping RPM are red flags. Brakes: test at low speed in a safe area — the pedal should feel firm, not spongy, and the car must not pull to one side. Tires: walk around and film each tire's sidewall and tread. Uneven wear suggests alignment or suspension problems. Combine this with an independent pre-shipment inspection for a professional report — the video call is your first filter, not the final verdict.

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.
