Car enthusiasts Jay Leno, Steve Carell, Adrien Brody, Timothy Hutton and George Lucas were among the 15,000 guests at Sunday’s Pebble Beach Concours d’Elegance.

“This is the Super Bowl of car enthusiasts,” said Leno, who chatted with car owners and spectators as he wandered the course that displayed more than 200 vintage cars. “It’s the chance to see cars you only read or hear about.”

For Pixar’s Jay Ward and Bob Pauley, the day also represented a research trip. “Pixar has been coming here for years and it was a great inspiration for the movie ‘Cars,'” said Ward, who wouldn’t confirm if the company is planning another sequel to the popular series. “But from John Lasseter down, we are very passionate about cars at Pixar. We even have our own employees car show every year on our grounds.”

The night before at the auction held by Gooding & Co., Leno appeared on stage with Secretary of Defense Leon Panetta to auction the star’s Fiat 500 Prima Edizione for $385,000, with all proceeds going to the Fisher House Foundation. A 2008 Tesla Signature 100 Roadster owned by George Clooney went for $99,000, proceeds going to the Satellite Sentinel Project.
