Auto lots are filled with used cars in New Jersey, but that doesn’t necessarily mean that the cars originated in the Garden State. As the recent flooding in Georgia shows, nature can have an affect on previously pristine vehicles.

That’s why buyers will want to check for a couple of things with some used cars, to ensure that the car they buy is safe for use. Many businesses will inform potential buyers of vehicles with salvage titles or flood damage, but caveat emptor.

A used car in New Jersey that has completely new interior materials should raise a red flag, according to some automotive experts, as should one with excessive rust or corrosion in the undercarriage and spare tire holder.

Other tips include ensuring the electrical system functions properly and using one’s nose for any moldy smells that could be a sign of previous water damage.

“Flood-damaged cars that are not structurally or mechanically sound could be repaired, re-titled, and sold to unsuspecting buyers,” notes Jason Day, vice president of one used car retailer.
