When Zipper gives Marnie a ride on his Harley, they leave Du-Par's Restaurant in the Fairfax neighborhood heading north on Fairfax, then in the next shot are shown going north on Van Nuys Blvd. crossing Magnolia Blvd., which is over ten miles north in the San Fernando Valley. After that brief shot, they are shown sitting on a bench south of the Santa Monica Pier. Santa Monica is nearly due west of the Fairfax area. Unless the BMW dealership in Sherman Oaks paid for a product placement, there's no reason for them to have gone so far north.
