Perspectives from a Spring, '07 reservation holder:
Interest has clearly waned in the Sacto and bay area. Back in early '08, there were dealer events, aftermarket vendor events, the famous Lombard Street event, scheduled drives, etc. Had to wait a year-plus to get the car... Now---zip.
Original affecianados have left the building. Sure, there's a few '08 scavenger owners around (...particularly, here on this board).
Most of the folks that actually reviewed, drove an overseas model, ordered, and waited for the US release have moved on.
The SF chapter may amuse you, although there's only a handful of members who actually participate.
