The story and photo fromhttp://www.wired.com/autopia/2013/07/pixar-motorama-2013/?viewall=true where you can see some photos, one of them is the Steve McQueen Jaguar XK SS from the Petersen Museum; the Mullin Museum, Jay Leno, Aston Martin, McLaren and Tesla all bring vehicles to show
Motorama is the brainchild of Pixar Animation head John Lasseter and Jay Ward, an art coordinator and character steward who has the enviable title of "Cars Legacy Guardian." He's well-suited to the gig, being a bona fide gearhead and all.
"This is a cultural event for Pixar," Ward told us while sitting on the tire of his 1929 Model A. "We get around 80 cars. About 35 employee cars and 40 guest vehicles."
