Maybe reach out to NayNay at Leonardtown Ford or DealerInsider at Chapman Ford, or both, to see if they can reach out to their Regional to get you some more visibility. Maybe even get you transferred somehow.
I'd keep pounding on Ford and escalate it. It seems they have worked a number of miracles for other people. I don't know about this late in the game though, to be honest. But I would be relentless.
I would call Ford Customer Service. I spoke with them back when we were trying to negotiate a volume group buy, and they were literally the worst. I can't imagine how many people they are screwing over to put Broncos on their lot.
