I agree for a year old model year that is not a good deal. Ford should be offering better rebates and incentives than that to clear inventory. Go in the last day of the month and try for lowest offer. Show interest but not excitement about the truck. Be prepared to head toward the door 2-3 times to get the price to drop.
Best times to buy are last day or two of the month, last day or two of the quarter, and (best but far away) last day or two of the year. They are trying to make monthly, quarterly, and yearly quotas.
Been a few years but I bought mine at the end of a model year just before the new ones came out and I got $14,000 off sticker.
