FILE - This Tuesday, Aug. 29, 2017, photo shows flooded cars near the Addicks Reservoir as floodwaters from Harvey rise in Houston. Auto industry experts estimate that 500,000 to 1 million cars, trucks and SUVs were damaged by floodwaters from Hurricane Harvey. Most will have so much water damage that they can't be fixed, and insurance companies will declare them total losses. Yet the damaged cars could be retitled and sold to unsuspecting buyers nationwide. Experts warn against buying the cars because damage could be hidden for years before causing problems.
