you may wish to talk to susan (ladyguen) aka lady guendalina's closet... she has some experience with vans and station wagons.. she may have better advice.

I have a coworker that swears by ebay. He's more than once flown off to somewhere random to drive a car from someplace else back here for someone.
If you go that route, I can probably hook you up with a buddy pass to get to the car.
