I wouldnt fly out there to get it -- or god sakes -- drive out there. I can pretty much guarantee you with 99.99997% certainty that after you drive 1500 miles to pick it up it will have shipped out the night before no matter what you tell em.

Trust me, the second you leave to go fetch that car, there will be universal forces at work to ensure you are going to get even more buttjousted. Id swallow pride and just stick it out with these guys. Only other alternative is to contract someone else to deliver it.
