I agree with others - Intercity is the best... but they don't come to WA often. I am also trying to get a car sent here and originally placed my order through them. Waited 3 weeks; they couldn't fill the truck so they cancelled my order.
I just signed up Interbay Transport. They're a broker, but they are local, highly recommended, and only use trucks they have a history with. They were about the same price as Intercity.
