Moto International has been the true dealership for the people since I bought my Sport 1200 from them in 2009.  I also own a Norge and both bikes go to them for all service.  They know what they are talking about, care about your bike, and do exactly what they say they are going to do.  A class act with great people in the shop taking care of people who buy Guzzi's because they are Guzzi's.
