Craigy is correct about the "allocation" process. The term is sometimes thrown around loosely, and it's meaning gets construed.
Dealers who perform well with a certain vehicle (Raptor, in this case) are given "allocations" from Ford. This means they are granted the ability to order and receive a vehicle configured by them to their specs, based upon what they want/what they think will look and sell best on their lot. One dealer may receive 2 allocations, while another 15. This is mostly dependent on your volume from previous model years. In the Raptors case, it's 70% dependent on previous Raptor sales, and 30% dependent on the sales share of F150 nationwide (Region A shall receive x% of F150s produced, while Region B shall receive x%).
So, if it's safe to assume, if your dealer (at this point) is offering you a Raptor and talking specifics with you such as date, ect, then they are confident they are receiving an allocation. Maybe they received 8 in 2014 and sure that they will receive at least that many this time around. But from what I've seen, allocated models tend to be the loaded models that are charged a premium and look good sitting out on the lot. Catching the eye of the passer-by, drawing them into the dealer. Said dealer then makes the sale and gets a premium profit due to the premium price.
As we all know, the cheaper alternative is the ordering process, though it takes longer than walking onto the lot, it allows you to buy close to invoice pricing. And if the dealer plays ball, then this is the cheapest route for the Raptor since the alphabet plans and discounts are excluded. Customer ordered Raptors HAVE NO EFFECT ON ALLOCATION NUMBERS. The dealership will receive their allocations as produced (Allocations take precedence over customer ordered vehicles, parts/options depending), and your ordered vehicle will fit onto the assembly line as soon as Ford can make it happen. Again, a good time frame is 12 weeks after order placed with dealer. You will receive updates from your dealer as the process progresses. And there is of course a payment required upfront (5K, which goes towards your vehicle), in the event you back out of the sale prior to completion, and ordered an oddly outfitted vehicle they may have trouble selling.
What dealers also do is promise to save an allocation spot for a customer, order their vehicle to spec (much like the ordering process regularly), but then charge the premium price (5-10K over MSRP) for being one of the first vehicles out. Guarantees a dealer has a buyer for one of their allocated vehicles, gets money in up front, and they still make the premium profit. ****** for customer, but it's the dealers way to make money. Wouldn't recommend this route.
But there's been some good information said in this thread. We at least know now that the order banks will open sometime around 7/18. With specs and info to come before then. Still looking like November/December for ordered vehicles, since allocations are bound to hit lots in September/October, and ordered vehicles to follow. So they don't seem too behind. I myself plan to wait until around August/September and put my order in with a dealer willing to not charge more than $1,000 over invoice, then wait my 12 weeks and walk away happy with my Raptor once delivered. Should be exciting!
