For most of us, cars are an ordinary fixture of daily life. But then there are custom cars--literal labors of love. Supercharged hot rods, sublimely sculpted classics, flashy tricked-out lowriders, neon-bright "import tuners"--an eye-popping blend of fine art and mechanical know-how. In this episode, we trace the history, technology, and cultural connections between successive generations who have turned the common car into an American art form. We'll ride with hot rodders and lowriders and visit the speed shops and paint shops where ordinary cars become art.
