Since the Ford website does not explicitly say there is a limited sales area, I also assumed they were available nationwide. However, I have not been able to find any dealers with new FFE stock in the Phoenix area. The one dealer I visited said they don't sell them in Arizona but they could...
I'm not asking if it's possible, I'm asking you, FFE owners, if you would feel confident taking your EV in for service/repairs to a dealership that isn't in a state where the FFE is sold. Is the fact that they service the C-MAX and Fusion Energi models good enough?
One easy way would be to start a public Google Sheets document for people to enter their mileage and capacity. I don't own the FFE yet so I probably wouldn't be the most reliable person to host this.
