The series began as an ultimately unbroadcast
pilot in August 2009. This original preliminary version had 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. They were encouraged to spend the entirety of their £200, even if it meant using any leftover on small antique trinkets, with potential penalty for not spending enough by deducting a percentage from profits. In this version, the experts only interacted at the outset of the episode and at the final auction, and the episode was 'self contained' - i.e. it wasn't part of a week-long trip. Potential was seen in the format for a series, but several tweaks were made. 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 goal of spending the entire budget or being penalised, was also dropped. In the original pilot, each expert could nominate any proceeds to be donated to a charity of their choice; in the actual series
Children in Need became the solo umbrella charity for any proceeds. Filming of each episode of the series does generally take place within a single day, although the actual length of a day may be simulated, i.e. it may actually be filmed over several days, but within the timespan that a single day would allow. Although many episodes of the week-long trips are indeed filmed on subsequent days, occasionally there may be a day's gap filming between some episodes, to allow the experts time to tend to their own shops or auction businesses. The two included segments per episode where each expert will visit a local point of historical interest, are filmed a few days later, with the celebrities wearing the same clothes as in the rest of the episode so as not to break
continuity. ==Records==
