There are several Alfas in Thousand Oaks. And San Fernando Valley has some of the best Alfa mechanics in the US.
The Alfa Owners of Southern California (AOSC) is one of the biggest in the country. We hold driving classes, track days, and other events. Track /race days are all across the southern half of California, even including Laguna Seca in Monterey [Yeah, it has a new sponsor's name, but I'm old school, having raced Alfas in the late 60's]
The Northern California club is also a big one, and one of the best used Alfa parts suppliers is in the Bay Area.
Welcome to the great delusion! These are wonderful cars.
