Friday was Werks Reunion, an all-Porsche event including a concours and a massive spectator car parking display, along with some terribly expensive, and pretty terrible, food.
A few images from Werks Reunion:
Day 4 also included a walk down Cannery Row to see the Exotics in the evening. Although the crowd was quite a different demographic, there were some pretty special cars on display including more than one La Ferrari, and two Koenigseggs (a CCX and an Agera S). The Agera S was finished in blue carbon fiber and had carbon fiber wheels.
