We buy cars, CAR WITH ENGINE PROBLEMSSSSSS!!!

Ever since I bought the car on the 31 of January 2020 it's been more in a repair shop in this 8 months then it has been driven by me. One day on my way to work something went wrong with the engine, it sounded like a misfire. I formally informed the necessary people about the problem/s I have. My car got picked up end of May and was send to LDR engines and gearboxes in Montague Gardens. I was informed the was no compression in one of the cylinders and that one of the pistons was broken. I thought that must also be why I experienced drivetrain problems. I was informed that a whole new sub assembly wil be done on the car. The car was the for a whole month... I got my car back early July. Within the following week or so that I got my car back, I made contact with the guy who helped me and told him about an oily foam substance under water bottle cap and idling noise. I took the car back early August and that when they informed me the head gasket blew and the radiator. Up until today, Friday 18 September 2020 I don't have my car. I was told the car would be done but evertime there something new that needs to be replaced. If you buy a car at we buy cars make 100% about what you buy and what condition the car is in... Let the car be inspected by the original dealer, Like a BMW or Mercedes dealer if that's the car you want to buy.
