We are taking care of a deceased family member's estate and to get rid of an old vehicle we placed an online ad - we were asking $150. Someone responded and we accepted their offer - all via email. Now our extended family has decided that they would like to keep the old vehicle for sentimental reasons.
So we contacted the prospective buyer and told him that we are sorry but we are no longer selling the vehicle. His response was that we have a contract and that he will be filing a breach of contract. He claims he has already spent $200 prepping for the vehicle - materials to restore it. No money was exchanged between us and the vehicle never left our possession
Does the prospective buyer have a valid argument? Do the emails constitute a contract?
