Rust is a deal-breaker that photos can hide, so be systematic. High-risk areas to check: 1. Underbody and frame rails—surface rust is normal, but flaking or bubbling paint means advanced corrosion 2. Wheel arches and rocker panels—these trap mud and salt 3. Door bottoms and the trunk floor—water collects here; lift the trunk mat and look for dampness or repair welds 4. Around the windshield and sunroof drains—leaks cause hidden rust in the A-pillars Ask the inspector to do a magnet test: filler-repaired areas won't hold a magnet, indicating past accident repairs. A paint thickness gauge reveals resprayed sections—uniform readings around 80-150 microns are normal; spikes over 300 suggest bodywork. Cars from northern China (salted roads in winter) or coastal cities need extra scrutiny on the underbody. If structural members show corrosion, walk away—repairs rarely restore original strength.

We use a calibrated high-precision paint thickness gauge to take multiple measurements on at least 13 metal surfaces of the entire vehicle. The original paint thickness of mainstream Chinese models typically ranges from 90μm to 150μm. If any area exceeds 200μm or even reaches over 500μm, we will directly conclude that the area has undergone bodywork and filler repair.

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.
