Sold a DEFECTIVE vehicle

MOTUS SELECT which is the used cars dealer at Renault Edenvale sold me a defective vehicle. Bought the car on Saturday and whilst driving home realised that it is unstable on the road. On Monday I took it to HI Q for a check and they told me that the shocks are defected. Took it to TYREMART for a shock test and all 4 shocks failed the test. Took it for another workshop and got the same report. Contacted MOTUS about them selling me an unroadworthy vehicle and they do not want to take responsibility for the repair. I don't know how this car passed a Dekra test - something very ***** going on there. I literally bought a car that has to be parked off because it's not roadworthy!!!! PLEASE STAY AWAY FROM THIS DEALERSHIP!!!!! THEY WILL LOVE YOU UP TO THE POINT OF THE SALE, AFTER THAT IF YOU HAVE ISSUES WITH YOUR PURCHASE YOU WILL SEE WHO THEY REALLY ARE - THEY JUST WANT YOUR MONEY.
