They are a performance shop in the East Bay area that rebuilds old race cars, but I have been told they typically have a couple F1's in the garage for servicing.

They apparently sold one at some point http://vprace.com/carsales/carsales.htm
Anyone have any info on that one?

The car they sold was #016. The other car you might frequently find there was chassis #042, the former Carl Beal car which is now red. Both those F1s were owned by the same individual whose name I seem to have conveniently forgotten. Sauc3 and I met him in the paddock at last year's Monterey Historic Races at Laguna Seca where he was displaying #016 in front of the Virtuoso Performance transporter.

Last I heard, a couple of months ago, the owner (Scott Drnek, I think his name was) was on his way to England to get his shop officially certified as another McLaren service center. So there will be a service facility in Southern California (BMW in Oxnard) and in Northern California (Virtuoso Performance).

Is there demand for 2 in California?

There is demand for one in Northern Callifornia, yes. Plus, VP has several other streams of income, so this is adding another one without adding much cost. It is a completely different story from a shop starting up from scratch and planning to only provide McLaren F1-related services.
