Another vote for DAS. Minivan from VA to CA for $825 depot-to-depot.

FWIW, I think problems with shipping a car are 99+% caused by the loser jockeys that take joyrides to/from the depots, not the truck ride between depots. If you're going with a door-to-door service, take careful note of the odometer reading before and after.
