For those who don't know, Mike Levine is Ford's North America Product Communication Director.
The online order system should list ADM (Price over MSRP) if it's going to be applied. That order sheet, an electronic version of the order the dealer writes up, or a hard copy from the dealer should be sufficient.
Mike has done wonders for Mach E buyers when dealers tried to slap ADM onto orders after the fact. He has also eliminated some of the outrageous attempts at Lightning "market adjustments" and priority bribes we've seen here and elsewhere. However, as he says in his own reply, it's hard for him to help if there is no record.
