Good day tsikot, im a buy and seller for about a year. I recently sold a car to a guy from the province. I told him that the owner is my aunt and that she went abroad and she had left the car to me so that i can liquidate the car. I let him inspect & test drive the car, even told him to have a mechanic look at the car and inspect all the documents.
He bought the car and after a day, he called me and wanted to me to refund his money since he learned that he was already the 4th owner.
He was threatening to sue me for lying that the car is from my aunt.
Is there any legal basis for this? Should i give him a refund? He was also charging me for the change oil and other maintenance service he did to the car..
