Whilst filling up at our local garage yesterday a 4 track BMW pulled in towing a somewhat battered and green stained 2 berth caravan. I jokingly said to its owner at the cash desk that he had his work cut out in getting the caravan back to a usable condition. He laughed and said that he's just collected it from its previous owner for the sum of......£5....
Somehow doubt that the seller was based in Carnforth.....
