An early scene has a yellow school bus outside a museum in New York. Soon after, Margot Tenenbaum (Gwyneth Paltrow) gets off the second of two GM New Looks (probably fleet number 1102) in the livery of 'Green Line' to meet her brother off a ship:
Later in the film, she is seen kissing Eli Cash (Owen Wilson) on a bus, probably one of those New Looks, but the shot is too close to see much.
When Ritchie Tenenbaum (Luke Wilson) leaves hospital, he catches Green Line New Look 1102 home. The Green Line New Look Royal Tenenbaum catches after giving his wife a divorce is not identifiable.
