Nhalber, If you search this site and fordfocuselectric.com/forums you will find several posts that explain the rollout in terms of which states are getting the car and when. You can also purchase the vehicle from anyone of a number of dealers in the NY, NJ, VA, IL markets. Go to ford.com and follow through to ordering a vehicle. When you get to the point of putting in your email address, type in one of the above states. Then you can get a list of dealers and start calling to see if they have one in stock.
I believe Boston is a 1b market so it should be coming soon. But, I was too impatient and ordered from NY and received my car in May of this year. I drove the car home to RI from Ramsey, NJ.
Good luck,,,,
