The only thing I can say about the new place in Manassas is that their delivery drivers are great people.
My only interaction with that (VERY new) dealer was taking delivery of a bike for friend who was out of town. The driver said that the staff was trying to get used to the idea of being a motorcycle place, but that the owner was "extremely enthusiastic" about the bikes. Take that as you will.
