When there is flooding and damage to new cars on dealer lots as we have seen in Michigan and parts of the Southeast this year, water-damaged, new, cars can make their way back onto dealer lots.
There are unscrupulous vultures vying to buy as many (formerly) premium vehicles (Lexus, BMW, Cadillac) as they can at the lowest possible price. They will rebuild them as cheaply as possible and sell them back into the auction circuit. The auction buyer is their prey.
When these vehicles are sold back into the auction circuit, they are generally moved across the country, far from the location of the scoundrels that sold them. Purchased by some dealers and brokers, they are then taken to lots and sold as new or "almost new."
It would be unusual to find these at a reputable big-time dealership in your area. But there are car brokers and lesser dealerships who sell both used and new cars who will advertise these cars as new..
So, what is going to happen to a flood damaged car? The vehicle may perform admirably for a few months, and then it slowly evolves into a money pit.
This worry obviously also applies to all used cars.
What to do? Check the Vehicle ID Number and cross-check for any discrepancies between the title, ID tag at the base of the windshield, and the tag on the driver's door. Any differences could be an indication that the vehicle was given a new VIN after a flood total.
