Basically Massachusetts hates people from Out of State. I've bought two cars from MA, as a ME resident, the first was from a piece of shit dealer who made me buy the car via fedex and get a "transit tag" from Maine. Then the second car was from BMW of Peabody, who delivered the car to my door.

People in MA get their tags from the dealer, who has a runner who goes and registers the car for the owner at the BMV while they're doing paperwork. Its retarded.
