The winner is the expert who makes the greater profit over five legs, with whatever money is left in the kitty at the end being donated to the charity Children in Need.

This original preliminary version saw the two experts – David Harper and Kate Bliss – each driving a classic car, and free to roam where they chose within a "work-day" time limit (9 a.m. to 5 p.m.) to buy up antiques with their £200 budget, with the goal of making the most profit when entered into auction two days later.

It was decided to have the two experts travel around together in the same car, allowing for interaction between the pair, and to make the 'road trip' span five days, and with a more designated overall route.

The records for the largest profit on a single item, the highest sale price for a single item, and the largest total profit on one road trip is held by Paul Laidlaw, who in one of the 2017 series (Series 15, Episode 5) bought a Chambre Automatique De Bertsch sub-miniature camera for £60 and sold it at auction for £20,000 (a 33,233% profit).

It was set by Charlie Ross when in the 2012 series, he bought a chipped Staffordshire elephant clock for £8 which sold for £2,700.
