The biggest official car boot is The National Bowl site in Milton Keynes every Sunday which has over 6000 cars every week. People turn up at 3:30am and there are still thousands of people about. It has also produced a few treasures including a womans 50p tea set that fetched �50 at a local auction and then �50,000 at Christies or Sotherby`s. Not much good if you live in Dundee though!
