Audi A3 3.2
Where are you in Northern California that these cars inspired the breaking-out of a camera? I don't even bother with DB9s, Gallardos, Porsche Turbos, Contineltal GTs or Elises anymore.
I see Ferraris and Porches all the time but I never seem to be quick enough. But I am really taking photos of vehicles I like, hence the Fire department Ford Explorer a few pages back.
Lotus 340R from small local exotic car dealership
A crazy Lotus 7 replica, I believe I posted pictures of this a long time ago but I got some more shots of it. Its made out of CF and aluminum, its not road legal in the slightest, and apparently is too loud for one of the tracks they took it to.
Lotus Elite, I think.
Taken with phone camera, and the lighting conditions were very odd so the pictures are less than studio quality. Not really sightings, but they pictures of cars that I saw.
