It has been more than one year since Superstorm Sandy devastated the Northeast, but the effects of the hurricane are still being felt – especially on the roads. That is because a number of vehicles damaged by the storm and subsequent flooding have been passed off as high-quality and sold to unsuspecting drivers all around the U.S.

While these automobiles may look fine, they often have extensive damage under the hood and within the frame, and those issues often rear their head after a short amount of time with a new owner. These problems can be a hassle, but there are a few things drivers can look out for to avoid purchasing a flood-damaged car. 

"Flood-damaged cars end up going places where consumers don't suspect it," Larry Gamache, CARFAX's communications director, told Edmunds.com. "But as con men get smarter, we get smarter on how we deter it." 

First, prospective buyers should be sure to check the car's undercarriage. Any signs or rust or flaking metal that appears out of place may be a warning sign. Similarly, if the carpet or upholstery is discolored, it could be an omen of flood damage. Drivers should also examine the headlights and taillights for foggy buildup on the interior, and the engine compartment and trunk should also be checked for water lines or other giveaways. 

Another quality that may be a red flag is any unusual odors. A musty or moldy smell could be indicative of mildew in hidden areas of the vehicle. If there is an overwhelming scent of bleach, cleaner or air freshener, it could be a way of masking some kind of odor, so pay extra attention in those situations as well. 

One of the easiest ways to avoid cars that have been damaged by floods or water is to shop at an auction lot you trust. Places such as NJ State Auto are ideal, as it carried CARFAX-certified vehicles that are both reliable and affordable.
