We live in a cul-de-sac. Just had someone knock on our front door asking if the campervan is for sale. It's not (just spent £500 on getting it through the MOT for another year!), and there's no sign to suggest it is. I didn't recognise the man at the door nor his vehicle so he's not just passing. Could be visiting a neighbour I suppose.
Am I being unreasonable/ridiculous to be deeply suspicious of his motives...?
