In the Scrappy Races series, five teams - The Barley Pickers, The Megalomaniacs, Chaos Crew, Boat Buoys and The Green Goddesses - build road-legal vehicles capable of being adapted to take on a different challange each week. The first episode follows the teams on their initial build, leading up to the vehicles being put through the government roadworthiness examination and then a spin round the Scrappy Races test circuit.
