PROVIDENCE, R.I. (WPRI) — Tens of thousands of cars are at risk of water damage as the country approaches the halfway mark of hurricane season. According to a new report from Carfax, at the end of last year, there were about 450,000 cars on the road in the United States with existing flood damage. Patrick Olsen from Carfax said the company believes about 1,400 cars in the Providence area have been damaged by heavy rains. He said used car shoppers must make sure they are not buying a car with water damage, as these vehicles can run the risk of having expensive electrical problems and engine issues. Olsen told 12 News scammers have ways of making cars that have been submerged in water look brand new. "They're going to look like they're perfect," he said. "But in reality, these cars are rotting from the inside out."
