Sheldon and Peter are tasked with the ultimate automotive challenge - a classic car that's reliable enough for everyday use. They take on the first ever European Car of the Year, a Rover P6. Sheldon and Peter are challenged to track down the ultimate automotive unicorn. Client John wants a Rover P6 that's reliable enough to use as his everyday runabout. When Sheldon finds a car that's within budget, reliability does not come as standard. Leaking rear brakes and an unresponsive automatic gearbox mean there's a mechanical mountain to climb to meet John's expectations, whilst Peter also faces a tough challenge as he attempts to fit a completely new vinyl roof. The P6 was his Dad's car of choice, so it's an emotional rollercoaster for Sheldon, but has he let his heart rule his head?
