Most companies offering open or enclosed auto transport services and working directly with consumers don't own the car haulers. They are known as auto transport brokers. Even if they have a few car hauling trailers, they typically don't own enough vehicles to ship cars everywhere. As soon as the car transportation broker finds a client, they enter into a contract with an actual car carrier and stipulate the details of shipping your car. The car carrier can be a car transportation company or an individual owner-operator.
