"The best place to start is with a Carfax vehicle history report. We get information on branded titles from all 50 state departments of motor vehicles. You can also go to flood.carfax.com and search for flood damage for free using your 17 digit VIN. Also take the car for a test drive and have a mechanic inspect the car, to look for signs of hidden damage that may have not been reported or can't be picked up by the untrained eye," says Basso.
