Rust is one of the most underestimated problems in remote buying. Request specific evidence: photos of the underbody, wheel arches, door sills, and around the windshield seal; close-ups of suspension mounting points; and ideally paint thickness readings across panels (factory paint is typically 80-120μm; heavy patches suggest bodywork). Northern Chinese cars may have winter road-salt corrosion; coastal cars can show surface rust on exposed metal. Surface rust on exhaust and bolts is normal—structural rust on frame rails, subframes, or brake lines is a deal-breaker, especially if the car is headed to a humid or coastal market. Have the inspector tap suspicious areas during the video call: flaky or bubbling metal sounds hollow. Walk away if the seller refuses underbody photos.

Yes, but it will be downgraded. For vehicles that are out of warranty and have no claims records, we will require a more in-depth physical inspection and clearly label the details page as "Data Unavailable" to ensure transparency about the risks. These vehicles typically have a higher price discount.

Based on practical risk assessment, we strongly recommend setting aside 3% to 5% of the car price as a buffer fund for even the highest-rated used cars, to cover oil changes, new tires, minor shipping scratches, and local inspection labor costs.
