I saw a vehicle advertised on Autotrader by a private individual. Having entered into negotiation with him we agreed a price. I subsequently sold my car to finance the purchase and hired one as an interim temporary measure. I then booked a flight to travel to pick up the car I was buying at an agreed day and time. I kept the seller fully informed of what I was doing so he knew I was selling my car to buy his. He knew I was booking and paying for travel and he was aware of the costs and expense I had gone to. He has now told me he has sold the car to someone else for a higher figure and it is no longer available. I am therefore out of pocket for my travel, the HPI check I carried out and I no longer have a car; only the one I have gone to the expense of hiring. Do I have any sort of recourse to cover my costs and the inconvenience?
