Technically speaking, Raptor is not "officially" eligible for AXZ plan purchases. A/Z plan is a little under invoice and X plan is generally just a few hundred dollars above invoice after discounts and fees. The AXZ plan price is printed on the vehicle invoice; plan customers are entitled to see the invoice so they can verify that they're paying the plan price. Because Raptor is not eligible for plan purchases, I don't know if the plan prices are even printed on the invoice... anyone dealer staff know?
When a Ford employee generates an AXZ plan pin number, they receive an email after generating it and another email after the customer takes delivery of the vehicle. I don't doubt that employees are generating X plan pin numbers and that dealerships are accepting them and honoring the X plan pricing. What I don't believe is that the dealerships are actually submitting the X plan to Ford for reimbursement.
Like I said, I'm being technical about this and the customer probably doesn't really care if they "officially" used an X plan as long as they get the X plan price.
Regardless, with the current state of Raptor supply/demand, production/allocation, and the upcoming model year change of the F-150, I'm not sure many dealers will continue to offer X plan or near invoice pricing on 2014MY going forward. This is just my opinion.
