I wouldn't do it. Too much risk involved and not enough products in the range to make it worthwhile these days. Only a small percentage of products keep the range alive. While most major cities in Europe, not just the UK have a B&O franchise (apart from 1 that isn't franchised), you are now also competing against a number of growing AV shops selling B&O second-hand. If it was 20 years ago fine, but not these days. Domino's pizza or KFC franchises would be far more profitable although perhaps not quite as enjoyable! Good luck either way.
