Rick feels the need for speed as he races to nab a 1959 go-kart. Can he pave his way to a deal, or is he on track for a loss? Then, a collection of toys from “Jurassic Park” comes roaring into the shop. But are these toys as dino-mite as Chum hopes? Next, Rick and Chum head to the east coast to check out an 18th century cannon. Can they light a fire under the seller, or will the deal blow up in their faces? And later, Corey gets a chance at a rare Olympic boxing ticket signed by two of the greatest fighters ever. Will he land a bargain, or will it be a TKO?
