overheating BMW118i sport

<p>in March 2016 i bought a BMW118i sport from Park Motors in Welkom, free State. The sales man there Hennie Britz said to me that the car is in tip top condition and he was testing it himself. three weeks down the line the car stated to overheat. called BMW on call and they towed it to Newscatle got it back after a week and it overheated again, returned the car to Hennie to terminate the contract only to find out that the car had a history of overheating hence the previous owner sold it, The management of Park Motors refused to help me and treated me like grab, now im stuck with a useless car that is broken. please somebody help me out. I hate Park Motors and i'm very much frustrated.</p>
