I live in the West side, and I know that the Boxster is a tiny fish here in Merc and Bimmer-land. Every morning I see at least one or two Cayenne Turbos, plenty of 6-series, 7-series, SL500s, and loads of 911s. Never had any trouble with road-rage, and rarely get looks except by people that actually know me. The Boxster here is like owning a motorcycle: cheap, nimble, and basic for those that can (or have to) scrape by.
Kinda nice and yet humbling at the same time..but I still treat it like a Ferrari
