I used DAS Dependable Auto Shippers to ship my VX from Virginia to AZ in December, cost, $1000. They are ebay's officially sanctioned auto carrier, very good, reliable, etc...

They also have a real time web tracking thing so you can look up and see where the truck is at any time.

Plus you can get a REAL quote on their website without 10,000 followup emails and calls like the other dozen or so companies I contacted for quotes. Oh my god, they didn't stop calling & emailing for months! DAS didn't give me any hassles or sales pressure.
