ok... what about the fact that I have been using the car on a daily basis and there was nothing wrong with it then? I don't actually know if it was a campbelt, what if it was another part? Something I genuinely wasn't aware of??? What about 'sold as seen' - they had a right to take the car to a mechanic and have it checked which would probably reveal some hidden issues I was not aware of??? How can I defend myself in this case?

Firstly, thank you for reading my post.... Secondly, I'd like to ask everyone who can help for a post on my thread. I sold a car which, few weeks earlier had a new campbelt and a water pump done. The car was driving well and was in constant use. I sold the car as I don't need it anymore due to a job change. A couple who decided to buy it traveled about 120 miles to get it (on a train). They had a test drive, we agreed a sale price and they ended up paying via internet transfer. They left with the car and over an hour later they called to say they cannot drive faster than 40mph, one more hour later they called to say the car broke down completely and there is plenty of smoke coming from underneath the car. As I agreed to keep the insurance until end of the day for them, I rang the breakdown cover who attended to the vehicle, took them to a nearest safe place and left them. I found out from the insurance company that the recovery team suggested a broken campbelt (!?!) and that the car has been left on a petrol station and the couple rushed to the nearest train station to get back home which was 30 miles away! I texted the couple in the morning urging them to ensure they take responsibility for the car as it's their own property now and they should move it asap to not be issued with parking charges etc. They texted back saying they are giving me 2 options - 1 to take the car and give them the money back, 2 to deal with the dad of the girl who is a lawyer. I texted back saying that as far as I'm aware I have fulfilled my legal obligations as a seller and from now on would like to be contacted in writing. So, I have now received two emails asking to provide 'honest description of sale activities' and was given a deadline of 24 hours to do so. Everything I put in the ad was truth, at the moment of sale I was sure the car is in a good state and was absolutely shocked with what happened. I replied to the email with a very brief description of the events from that day stating that my knowledge as to what happened after the buyers drove away in the car is limited and I requested a full explanation as to why they want to take the case to court. I now have to deal with the person who claims to be a lawyer... Although I think I have done nothing wrong, and what happened is just a pure bad luck, I am afraid that there is a chance for the buyer to force me to take the car and give the money back! I actually don't know what happened with the car, I only know what was suggested by the recovery team.... I'd appreciate help and suggested course of actions as I am 100% sure the case will end up in court, with the difference that I don't have a dad - lawyer who can defend me for free...
