(ARA) - The summer's unrelenting rainfall could result in an increase in the number of flood-damaged vehicles for sale across the country -- even in dry areas! Those in the market for a used car should beware.

Many watery wrecks will re-emerge after Hurricane Charley and will eventually make their way back on the road. Auto insurance adjusters total the water-damaged vehicles, but that doesn't stop unscrupulous sellers from drying them out, polishing them up and putting them back up for sale.

Cars may also be repaired and moved to areas where consumers are less aware that water damage is a potential threat, creating a nationwide safety concern. In many instances, these mechanically unsound, damaged vehicles undergo minor repairs and are resold to unsuspecting buyers.

There are a few simple tips that consumers can follow to avoid buying a waterlogged wreck:

* Check the trunk, glove box, the dashboard and below seats for signs of water damage including sand, mud or rust. Check for frayed or cracked wires beneath the dashboard and make sure all accessory and warning lights and gauges come on and work properly.

* Examine the upholstery and carpeting. If it doesn't match the interior or doesn't fit properly, it may have been replaced. Discolored, faded or stained material may indicate water damage.

* Test lights (interior and exterior), windshield wipers, turn signals, cigarette lighter, radio, heater and air conditioner several times to make sure they work.

* Turn on the A/C and take a deep breath to check for musty odors from mildew.

* Visit a trusted mechanic and/or auto body shop for a pre-purchase inspection. Always get vehicles checked before handing over any money.

* Ask the dealer for a Carfax Vehicle History Report (or get a copy for yourself). Carfax reports show flood or water-damage titles and can reveal if a vehicle has been titled/registered in "at-risk" areas where flooding has occurred. Carfax also offers a Buyback Guarantee. Cars purchased with Carfax Vehicle History Reports that do not contain DMV-reported incidents (salvage, fire, flood damage, odometer problems, lemon history) may be eligible.

Whether from hurricanes like Charley or from heavy rainstorms, cars that are submerged in water for any significant length of time -- whether a few days, a week or longer, can have substantial mechanical and electrical problems and rate low in safety and reliability. This can end up costing the owner a considerable amount of money. Being a smart shopper can reduce your risk of buying a clunker and save you big bucks.
