Another vote for Reliable :

I have used them with good results .
Ya just have to make sure they can give you a firm pick up and delivery timing window - sometimes your car is waiting until they have a full load . They were a couple weeks off moving a friends Cobra from Detroit to Virginia, as they said " we have nothing else going that way at the moment ".
Confirming Slider 701s comment : I too was with Ford and Reliable was often used by the Detroit 3 for specialty car hauling . Bill
