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.

Basic perception functions (like Adaptive Cruise Control ACC, Lane Keeping Assist LKA, and Automatic Emergency Braking AEB) rely on the vehicle's local radar and cameras, and can operate normally overseas. However, advanced features that heavily depend on high-precision maps and cloud data (like Navigation on Autopilot NOA and Full Self-Driving FSD) cannot be activated overseas.
