Chris;
Might want to use InterCity Lines real time quote system to establish a base for cost comparisons

ICL, as does most other professional car transport companies has GPS tracking for the truck. Also, they called me a number of times during their trip to let me know their estimated time of arrival at my driveway.
Not implying that ICL is any better than other companies, just happens to be the only company I had experience with.
