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. The guys next meet Jim's awesome collection of original automotive advertising art. 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. And Mike makes a sweet deal with a museum curator to ensure that a rare piece of car history finds a permanent place of honor.
