Gary,
From what I have read, the Menlo Park C&C (Cars & Croissants) events are open to all 'exotic and performance' cars ... whereas the Santana Row C&C events seem to be more for 'exotics' only. That's not to say you can't rumble up in a McLaren volcano orange Cobra ... that's seems pretty exotic to me. Let us know how it goes.
From the C&C web page ...
New for 2014, 100|OCT is proud to introduce monthly meets for exotics and performance cars.
On the first Saturday of the month, from April to December, from 9am to 12pm, 100|OCT‘s Cars and Croissants will take place in Menlo Park so as to attract car enthusiasts ....
On the fourth Saturday of the month, again from April to December, from 9am to 12pm, 100|OCT‘s Cars and Croissants will take place in San Jose, on Santana Row‘s main street. As the space there is more restricted, 100|OCT‘s Cars and Croissants on The Row will be exclusively for exotic cars!
