Cheque fraud with a sale 
As a seller, you must also guard against fraud: when selling vehicles, sellers are often given cheques which are not covered. Therefore, we would strongly advise you not to accept cheques as a means of payment!
If you – as the seller – receive a cheque (generally sent from abroad) where the amount is more than the agreed purchase price, then it is more than likely to be an attempted fraud. Do not, under any circumstances, transfer the difference back, as the cheque is most probably stolen or a false one – even if first enquiries do not arouse any concerns.
