Scouring a mind-blowing collection of vintage petroliana in Massachusetts, Frank breaks a sweat and the bank when he uncovers the holy grail of oilcans. Later, in Rhode Island, the guys get a once-in-a-lifetime invitation to a mammoth Newport mansion where they bid big money on a series of rare gems.

Mike and Frank are in Springfield, Massachusetts, the birthplace of Indian Motorcycles. While there, the guys chase a legend that could be a real buried treasure, and drop a massive amount of cash on a stash of classic motorcycles.
