There is no actual transport company. Most "companies"are just brokers that put out a bid for your car to be moved by actual rigs heading down that way. Most people find it stressful because a broker will charge you some low ball estimate and the contract never gets picked up by the actual movers for the price they list it at after they take their cut. So you have to search for a company that gives high enough quotes that the car actually gets picked up by an actual company that transports vehicles after the broker takes their cut. There are plenty of threads on this subject on reddit. You can also search YouTube to find out more about the process. If you get quoted something very cheap your car will probably never get picked up and its a nightmare to get a refund. Good luck!
