American Restoration, Vol. 4

As the clock ticks, can Rick and his team deliver the gold-star quality restoration and satisfy the high expectations of collectors? From restoring an 1800's Zeno gum machine to repurposing Sammy Hagar's vintage fridge into a rum dispenser and restarting NASCAR driver Greg Biffle's muddy 1970's Montesa motorcycle for a race to the finish, watch as they face unseen challenges and tackle a variety of weird, rare, and valuable objects.
