Maintain objective expectations. Vehicles over 5 years old inevitably show signs of decreased paint gloss, slight aging of rubber seals, irreversible patina on interiors, and surface rust on chassis components. As long as core structure and mechanical failures are not involved, these are normal depreciation characteristics over time.

If there is a minor leak in the lines due to bumps, it is possible that the cooling may not work upon arrival. This is a normal physical loss. The cost of vacuuming, pressure testing, and recharging refrigerant at a local auto repair shop is low and is the buyer's responsibility.

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.
