Down at Brighton there is a big carnival at the finish line. I'm talking, rides, games, stunt men, and stalls selling stuff. All the cars also are lined up and put on display with their hoods up and what not.
It was a very cool day and something I highly recommend!
Here is a link that tells you a bit more and photos/videos below.
Here is a video of the oldest car being crank started and the engine. Sorry about the people, lots of interest.
