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.

Flood cars are common after heavy rain seasons, and the damage often shows up months later in the wiring and electronics. Here is how to check before you buy. First, ask for the insurance claim history using the VIN. Flood claims are usually recorded, and any mention of water damage, interior drying, or electrical repair should stop the deal. Second, inspect the interior yourself or via video call. Pull up the carpet edges and look for mud residue, water marks, or rust on seat rails and seatbelt buckles. Seatbelts that retract slowly or have a musty smell were often submerged. Third, check hidden cavities: the spare tire well, glove box, and under the trunk lining. Silt or a tide line there is a strong flood indicator. Fourth, look for condensation behind the instrument cluster and inside the headlights. Persistent fog in the lamps is a classic sign of water immersion. Finally, an OBD scan can help: flood cars often store scattered error codes across unrelated modules (airbag, ABS, body control) because corroded connectors corrupt the network. If several of these signs appear together, walk away. Flood damage is almost never worth repairing, and it will haunt the car's electronics for its whole life.

Most exporters offer a limited warranty of 30 to 90 days covering major mechanical failures (engine, gearbox, electric motor), but only if you can prove the fault existed before shipment. Cosmetic issues, wear-and-tear parts (brakes, tires, clutch) and damage caused by improper local maintenance are almost always excluded. What is realistic to claim: · Engine or transmission failure confirmed by a licensed workshop within the warranty window, with a diagnostic report. · Undeclared accident or flood damage discovered after arrival (strongest case, keep the inspection report and photos). How to protect yourself: 1. Get the warranty terms written into the contract, including claim procedure and response time. 2. Have the car inspected locally immediately upon arrival and keep all records. 3. Communicate claims in writing (email) with photos and reports attached. Treat the warranty as a backup, not the main protection. A thorough pre-shipment third-party inspection matters far more than a paper warranty.
