I used Nation Wide Transport Service and they did a great job and for a decent price. I was charged a little over $800 for 3 day service in a covered shipper from Scottsdale AZ. to Everett WA. http://nationwidetransportservices.com/ Good luck.
I used OK Auto Carriers. They were also totally enenclosed and got my Buick from AZ to Federal Way in two days. No joke! The drivers names is Alex and he was awesome!
