I've actually had pretty good luck with Craigslist but it can take some patience to find something worthwhile.

Anyway, I suspect that's a repainted frame and a set of Bianchi stickers somebody got off Ebay. There's no sticker that shows frame materials and nothing that indicates what model it is. It's hard to tell but the dropouts look stamped rather than forged.

The wheels and fork are clearly not original, - which might be just as well.

Bianchi or not that particular bike is way over priced for this part of the world. Maybe old cheap road bikes fetch that much in Orange County. I don't know.
