Only one in Tucson. The dealer in Prescott ( used to be EP&F ) is a long time Guzzi dealer and they changed their name. The one in Tucson ( on any Moto) is fairly new.
Steve Spreter Retired and Renaissance has been closed for about a year.
I've had no dealings with either.
I believe
GO-AZ in Peoria, AZ is now an official Guzzi dealer.
EP&F (Encore Performance & Fabrication) is now
Powersports Outlet, and they have a new shop near downtown Prescott. Matt & team there are very reputable for service on all brands of bikes.
Have not heard anything about the Tucson dealer yet (??). Need to visit there one of these days.
