Just saw the ford letter stating they re issued any 2022 invoices to reflect the lowered adjustment.The build sheet looks recent though since it has the bluecruise adjustment? I heard any update past 12/31 in Fords system excludes the price protection so would check with your dealer.
Side note I wonder how many dealers are going to pocket that $800 instead of passing it on, I highly doubt it will be reflected on stickers.
