I used
www.shipvehicles.com to do a quote request and then went with the lowest quote... in my case
AAALL STATES AUTO TRANSPORT. It cost me $750 total from CO to NY.
I was quite satisfied with both the service and the price. The guys who work there are great to deal with and will try to save you money.
The only problem was that the truck was a few days late for pickup due to a scheduling error. But other than that, I'd recommend them any day.
