Can you build your own amphibious car? Can you make a space shuttle from a Reliant Robin? Can you destroy a Toyota Hilux pick-up? In the course of finding out, Jeremy Clarkson, Richard Hammond and James May have risked their limbs, their lives and what little is left of their dignity. Top Gear: Ambitious But Rubbish re-lives many of the greatest and boldest endeavours in all their splendour.
