Experts James Braxton and Mark Stacey travel from Norfolk to West Sussex in a classic open-topped MG. They set off from Kings Lynn in search of antiques they can sell for a profit at auction in Diss. James's outlandish style is to spend big on expensive items to make even bigger profits, whereas Mark is more cautious and wants small bargains that just might turn out to be big sellers. Will either one of them make money at auction? And will the old car keep going, or will the British weather get the better of them?
