Thinking more about this, since you have to take the car on the West Coast, I would absolutely leave it there. Lots of well-heeled folks in CA, many of whom are also golfers. The truck will start to depreciate instantaneously, so the fewer miles the better and I wouldn't want to spend the money to ship it to the east coast. Someone mentioned Barrett Jackson, and an auction like that may actually be the best idea.
Another good option might be Vegas, but then you'd be in for transporting there as well.
Lastly, how soon can you get access to it? The Pebble Beach Concours is in 42 days. LOTS of money will be in town for that event. And there are many auctions that happen then, for that very reason.
