Pete, you are a brave man, given that Di has dropped into the Forum from time to time !
Perhaps some comments about a fine wine being "young & cheeky", then maturing into something priceless like a "Grange Hermitage" might save your bacon !!
BTW : Given a blank sheet of paper (ie, if I was single), I reckon that the optimum approach to the enjoyment of these assets would be by way of the rental model - no depreciation problems with that one !
As a friend of mine once said : "I don't pay them to stay the night, I just pay them to go away in the morning" !!
Kind Regards,
Peter D.
