The shop is busting at the seams so Mike and Frank task Danielle with getting a bid to expand the building while the guys head to Michigan hoping to strike automotive gold in the heart of the America's car capital. Clearing the contents of derelict storage lockers, Brian's sprawling auction house is a picker's playground where Mike and Frank get junk drunk as they dig deep and get a Hubley cast-iron motorcycle sidecar toy, Pabst blue ribbon ceramic beer bottle display, Bolex video camera, Detroit Lions bobblehead, Star Wars C-3PO scale model, Detroit Tigers figure, Vindex cast-iron bulldog electric cigarette lighter, and matchbooks. The guys next meet Jim's awesome collection of original automotive advertising art that yields a Honda 450 motorcycle painting, a battery-operated scale model of the Uniroyal Giant Tire Ferris wheel, Syd Mead concept car paintings, and a folk art tractor. And Tony wants to thin out his collection of old car and gas station memorabilia. Hoping for a lottery-style return, Mike and Frank battle it out for a collection of motometers before uncovering two items, each with a jaw-dropping pedigree, a Charles Lindberg coat and a 1908 Oldsmobile-manufactured leather license plate which Mike makes a sweet deal on with the curator of the R. E. Olds Transportation Museum[2] to ensure that the rare piece of car history finds a permanent place of honor. (thetvdb.com)
