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.

You can watch the car through live streaming or VR, or entrust a local third-party agency to inspect the car for you. Transparency about the car's condition is the foundation of trust.

Mainstream Chinese automakers rarely publish official English versions of their underlying circuit diagrams. We can provide some models' original Chinese technical documents (PDF) for B2B clients, which you will need to translate for your local mechanics using translation software.
