I'm not positive about this but I think that the San Jose one moved to Santa Cruz and then eventually closed.
The place that was in Santa Cruz is gone for sure. It used to be at the end of Pacific Avenue. The guy let me take one of the cars for a free spin around the block when I went in to chat with him once. I think I also bought a center console from him for like $20.
Unfortunately that place has been gone for a couple of years now.
