In Devon, Tim Shaw and Fuzz Townshend take on the task of restoring a 1958 Messerschmitt KR200 Bubble Car for classic car fan Sam. But the tiny car - a three-wheeled, rusting heap that has lain dormant for decades - proves to be a massive restoration project. The single cylinder, two-stroke engine hasn't started for years and needs a full rebuild, and the microcar's shattered acrylic canopy needs replacing. However, finding one proves difficult.
