It's definitely X plan. The owner told the sales guy to give me X plan and I asked the guy that orders to send me the actual build sheet so I can sign off. The build sheet lists, invoice, A/Z plan, D plan and X plan. There was only a $42 dollar increase with X plan over invoice so as far as I'm concerned X plan is invoice pricing. Now A/Z plan was definitely the cat's meow which was $2312 under invoice. Don't know what you have to do to get A/Z plan but that's for sure the way to go. I think maybe Ford Retiree's get that A/Z plan?
I bought my 15 F150 from the same place and have the same build sheet and sales sheet for my truck and I did have to pay a $598 doc fee. It was not any plan pricing for my F150 just 1k below invoice price. So looking at the 18 Exp sales sheet that doc fee isn't on there so I have to assume with their X plan that they probably don't charge the doc fee. If they do when I go to pick up I will bring up the $100 max.
My wife initially wanted the limited due to the bucket seat 2nd row option but that's the only thing she cared about over the XLT trim and we couldn't justify the extra 5k or so by going with the limited trim with bucket 2nd row option so she settled for the XLT 302a and sacrificed that one option . Other than that she got all the options she wanted and even let me talk her into a 4x4 versus 4x2 so at the end of the day happy wife happy life as i'm sure those with wifey's know ;-).
