All too often, used car dealers may try to sell flood-damaged cars without letting the prospective buyers know, and the Insurance Information Institute (III) is helping buyers to be on the look out for signs of flood damage.

One of the easiest signs to spot is if there is mildew, debris or silt in unusual places in the car. For instance, if they make their way into spots such as the carpeting, trunk or around the engine compartment, it should tip you off.

Some more subtle hints come in the form of changes in upholstery. Faded fabrics or water stains are an instant indication, and discolored seatbelts can be telling as well.

"To avoid inadvertently purchasing a flood-damaged car, it is important that you only buy a used car from a reputable dealer, have a certified mechanic look for flood damage and check the car's VIN number by using a credible industry database," said Jeanne M. Salvatore, the consumer spokesperson for the III.
