How to Check for a Flood-Damaged Car
To check for a flood-damaged car, inspect for musty odors, water lines, silt in hidden areas, rust on unpainted metal and corroded electronics, then check the title for a 'flood' or 'water damage' brand. Flood damage often isn't obvious because sellers clean and dry cars before resale, so combine a physical inspection with a title check and a VIN decode. Water-damaged cars can develop electrical and safety failures long after the sale.
