Thousands of unsold foreign cars are sitting at U.S. ports because dealers don't want them.

Foreign cars delivered to this port in Long Beach, California would normally be loaded onto trucks, and then delivered to dealerships.

But American dealerships don't want them because they're having a hard time selling their current inventory.

The Commerce department reports car sales are down nearly 15% this year.

And for the first time, automakers Mercedes-Benz, Toyota and Nissan have asked to lease space from the port to house the vehicles.
