John,
Although there is no direct support in SLO, you are relatively close to the Central Coast Chapter, which is more or less located in Santa Barbara, just to the south. There are several GTV6 owners there and the area that you are in is a haven for other Socal Alfisti to tour to; so keep your eyes open, you never know when you will see a procession of Alfas cruise through on their way to Paso Robles or Monterey.
