Original ad stated clean and tidy I put a link to it on here.I was never aware of a problem beforehand, the buyer told me there was a leak and investigated it finding damp.he asked for £200 to fix at first then said £150.The van never showed signs of damp or leaks prior to sale.I received messages asking if damp free and as far as I was aware it was and messaged this information back to a few interested people.
