What are the characteristics of a flood-damaged car?

[MacRyder]

Characteristics of a flood-damaged car: 1. Unusual odor: Check for a musty smell inside the car. Flood-damaged vehicles often have a musty odor in hidden areas such as the floor mats, trunk mats, and under the seats, which is difficult to remove and usually leaves evidence. 2. Internal rust: Inspect screws in hidden parts of the vehicle for rust or signs of being replaced; pull out the seats to check for rust or sand in the tracks; extend the seatbelt fully to see if there are water stains or dirt at the end. 3. Weak button rebound: Press the functional buttons inside the car. If multiple buttons feel sticky or have weak rebound, these devices may have been submerged in water. 4. Repair records: Check the maintenance records at a 4S shop to see if there are any engine repair records. If there are, it usually indicates a major accident or flood damage.
