It's the end of the tour for seasoned road tripper David Harper and his debutante rival Hettie Jago as they steer the 1980s Mercedes 280 SL towards their final auction. With money to spend and one last chance in the saleroom, they hit the antiques shops and emporia of Lancashire. Hettie invests in varied lots from inkwells to hatstands, then blows the remainder of her budget on one spectacular big-ticket item in a bid to outwit David. And isn't it typical? David waited all day for an urn stand, then two came along at once. Then it's on to their last showdown. Will Hettie, the student, become the master? Or will David hold on to win?
