Documenting the 2011 Gumball, Number 13 follows the story of MTV's Dirty Sanchez. Driving alongside the most incredible array of supercars ever seen together Lee Dainton and Matthew Pritchard embark on the 3000 mile journey in their humble 20 year old VW. From London to Istanbul, travelling across 13 countries in just 7 days with insane parties each night takes its toll on the Dirty Sanchez duo and the rest of the Gumballers.
