Catherine Southon and Philip Serrell are travelling along the beautiful Cornish coastline in a classic Citroen DS20. Before the auction in Bristol, Catherine heads to Porthcurno to see first hand the incredible cables that stretch from this little village, along the sea bed, to South America, Australia and India. Meanwhile, Phil goes for a ride on a replica of the Puffing Devil, one of the first steam-powered vehicles in the world.
