Pebble beach alone is $100, Monterey Historics is 35 or 40 per day (Max of 3 days). If you park in one of corals there's an extra charge usually that the organizers pass on.
Usually I do Saturday at Monterey and Sunday at Pebble. I definetly need to check out Concourso Italiano on Friday also. Which is another $35.
Oh...and yes I took all the pics.
