Sold car but after 3 days old fault came back and buyer wants refund
Hi I have sold my car privately and was sold "as seen". All reciepts were viewed by the buyer, except 1, this was for on oxygen sensor which has been replaced it was not intentionaly hidded but misplaced in my new cars logbook. Previously the engine management light was on showing a fault and to our knowledge it was fixed and sorted. Its now been 3 days since it was sold and the problem has re appeared. The buyer is now wanting to give the car back for a refund as he did not see this missing receipt and therefore would not have bought it.
Am I liable to refund him?
