We presently have our van for sale on Caravan finder. We have been approached by a Polish person who only wants email contact. He is requesting more photos of the van (already four on there and he does not specify exactly what photos he wants). Moreover he is requesting a scan of the CRIS document be emailed to him. We have gone back saying we have decided not to sell as we are suspicious. Does anyone think this is dodgy or am I over reacting?
