Try to avoid using a broker, they will take the lowest price and there is no recourse if damage occurs, ask me how I know. If the car is important to you, pay the double price to a known shipper like Intercity or Reliable.
And avoid U-Ship, it's the wild west when it comes to shippers. A guy bought a car from me, didn't want to use my shipper, he saved $100 by using U-Ship. His trucker was a dude in a converted motor home that was full of furniture. He un-loaded the furniture, loaded the car, then loaded the furniture on top of the car.
