If you haven't heard of the Hupmobile or if images of a vintage roadster make you crave your torque wrench, then take a cruise through classic auto history with two in-depth peeks into the mechanical passion that changed the way America lives. Come along for the ride as "Oldest Autos" explores the early challenges of turn-of-the-century automakers, and "Orphan Cars" salutes a love of forgotten models like the Studebaker and Edsel.
