unroadworthy car

on the 19/03/2014 we bought a Cherry Tiggo at Mac Carthy. and we started encounting problems on the 9/05/2014, the brake lights and ABS light was always on and we took it back to the car dealer. they told us they forgot to reset the lights during servicing of the car. But we had the same problem on the 29/07/2014 but this time the car didn't even want to start ,therefore it had to be towed back to mac carthy. The manager by the name of Pieter told us the car had a fuse problem and they will fix it. then 21/10/2014 we took back the car again to mac carthy with the same problem, then we suggested they give us another car that won't give us problems but they told us they can only settle the market value of the vehicle and we must pay the difference. As we speak now the car is still with them and we are still paying a monthly instalment of the car we don't have.<br> Contact details of the Managers who were assisting ***.Email address: [Email Removed] and [Email Removed]
