Dear Liz: You’ve been writing recently about how to find a good, cheap used car. Can you write about how to research whether a car has been damaged in a flood?

Answer: Carfax, which provides vehicle history reports, offers a free flood check in the “resources” section of the site’s press center.

Flood-damaged cars that have been totaled by insurance companies are typically sent to auto recyclers for dismantling but some wind up back on the market. These cars are supposed to have salvage titles that make clear their dubious histories, but it’s relatively easy for unscrupulous sellers to register the car in a different, more lenient state that obscures its past. This is known as “title washing.”

Carfax’s service can help you spot the damaged cars, as can your own senses. A car that smells like mold or strong cleaning solution (to cover up the mold) is a bad sign. Carpeting or upholstery that’s obviously newer than the car can indicate it’s been replaced after flood damage. Look in the glove box and under the seats for mud or silt. A sagging headliner on a newer car is another red flag.

A good mechanic can help you spot problems if you’re not sure. If the seller won’t let you take the car to your own mechanic for inspection, don’t buy it.
