I paid him on the phone and he did not even sent me a receipt for a deposit and I have never sign any document from him either. I let him take the deposit because thats what most companies do. As soon as I told him that we wont be able to purchase the car anymore he was saying that I was wasting his time and he could not sell it to other people so he requires me to either buy it or pay him 10% of the car price or else he will take me to the court. I'm not sure but I think what he is claiming is invalid?

The car was to purchased in the UK and the dealer is claiming 10 percent of the selling price to be paid for his lost otherwise he will take me to the count. No contract was signed though

Yes the car was to be purchased in the UK

I need help! My family member in foreign country asked me to put down deposit for this used car and then it has been 3 weeks and in the end he decided not to buy the car because old car cannot be imported into the country. Therefore, we let the dealer take deposit of 1500 pounds but I got an email from the dealer that he will take me to the court and sue me for him losing his profit to sell the car to someone else. The email implied if I dont buy this car he will get the lawyer to sort me out in the court. I have never got a receipt for the deposit payment and even order form or any form to sign at all. Will he actually be able to use this against me in the court?
