 Severe flooding from recent hurricanes and other storms has left hundreds of thousands of cars, trucks, and other vehicles unsafe to drive. But far too many of these flooded vehicles will end up back on car lots or up for sale online with no indication that they were in a flood. If you're in the market for a used vehicle, be on the lookout for flood damage and make sure you have a qualified mechanic inspected before you buy. The free VIN check service from the National Insurance Crime Bureau is a good place to start to see if a car has been in a flood. Go to www.nicb.org to check it out.
