If you really want to see some amazing cars, check out the 17th annual vintage car races at Pacific Raceways on the 1st-3rd of July. There are always hundreds of great vintage cars, many of them racing. The races aren't a parade, either. Those guys really put the pedal down. The whole thing is organized by SOVREN (http://www.sovren.org/) and the proceeds benefit Children's Hospital. I have gone for the last few years and always have a great time.
