It depends on the car's value, type and destination. RORO means the car is driven onto the vessel and secured on deck or in the hull. It is usually cheaper per car and does not involve container packing fees. The downside: the car sits exposed to salt air for weeks, and RORO service is limited to ports with dedicated terminals. Container shipping (one 20ft or 40ft container per 1-2 cars) costs more but gives much better protection. It is strongly recommended for electric vehicles (battery safety regulations), luxury cars, and vehicles going on long voyages or rough sea routes. Practical tips: whichever method you choose, ask for the car to be shipped with a full battery charge disconnected at the terminals, tire pressures adjusted, and a condition report with photos signed at loading. For EVs, confirm the shipping line accepts used electric vehicles and what state-of-charge limits apply.

Testing is mandatory. Troubleshooting electrical devices in the car is part of the standard procedure. We will test the window lift motors, mirror folding, air conditioning compressor and fan, electric seat tracks, etc. Any stuttering or failure of electronic components will be recorded.

State of Health (SOH) tells you how much of the original battery capacity remains. Here's how to use it. Reading the report: SOH is usually shown as a percentage of original capacity. A car at 90% SOH retains roughly 90% of its original range. Also check for cell imbalance (voltage spread between modules)—a low SOH with balanced cells is often fine, but high imbalance causes sudden range drops and charging problems. Acceptable thresholds: for a car under 3 years old, expect 90%+ SOH. For 3-5 years, 85-90% is normal. Below 80% SOH, the battery may soon need replacement—replacement costs can exceed the car's value, so negotiate hard or walk away. How to verify: don't trust a screenshot. Ask for a live screen recording of the diagnostic app (like the brand's official tool) starting from the car's VIN page. Cross-check the fast-charging curve: a healthy battery charges at near-peak rate up to 60-70%; a degraded one tapers early. Finally, remember that hot climates degrade batteries faster—if the car spent its life in southern China, scrutinize SOH more carefully.
