Ah the perils of buying and selling! Recently used eBay to sell a caravan. Honest ad saying it had damp. Bidding went silly and as it transpired the winner cancelled. Offered for second chance and one person wanted to lower his offer. I decided he wasn't having it on principle! Readvertised bidding when high again. Did a whatsapp viewing to the eventual winner prior to his highest bid He said he was buying it to put the fittings in a van then never turned-up. The person who actually bought it was the only one who viewed it and I sold it to him for a lower price than his bid. There's seem to be people out there just trying to bid prices up for the fun of it!
Agreed. Make sure you get the correct size otherwise you'll need to change the hoses etc. Prices on ebay vary quite a lot for the same make so check you don't pay too much.
