It's the glittering finale with audacious auctioneers Charles Hanson and Natasha Raskin Sharp. They've travelled south to Hertfordshire in the super glam 1932 Riley Monaco, the oldest set of wheels to ever grace the trip.Charles has got over a grand to play with, and he aims to spend like there's no tomorrow. Not only does he take part in a whirlwind shopping dash, he also finds time to travel to Waddesdon in Buckinghamshire and the home of Baron Ferdinand De Rothschild, one of the greatest collectors of fine art in the world. But Charles discovers more about this Victorian gentleman's love for the natural world, and a 19th-century rarity.Brimming with confidence, Natasha is also pumped up and ready to go for the final furlong of the trip. Leaving only 36 pennies in the kitty, she spends over £300 on items including a Victorian ink and wash painting of a grumpy girl and a stunning 19th-century Italian bronze vase. She makes a trip to 1960s suburbia in Ware to find out about a Georgian gem created by a Quaker poet.Who will raise the Road Trip trophy aloft as this week's ultimate winner?
