Yeah, same in AZ. That "one deal" bit was an issue for me as I would have been happy to turn over the trade at the time of ordering. Since that would have lost the sales tax credit, I was very happy to negotiate a guaranteed value for my trade-in. (I held up my end of the bargain, barely drove it for the 3 months I waited - just enough to keep the oil up and seals wet.)
