I'm guessing that price is for open transporter, which may be appropriate given the value of the car, but the weather across the country can be nasty at this time of year. You seem to be a bit of a perfectionist in what you're looking for - you might want to see what the upcharge would be to go to enclosed. I'm having a car shipped from D.C. to Utah right now, and I waited an extra few weeks to get it done in an enclosed transporter. It's worth it for a nice car during the winter (plus the dealer's paying).
