We buy cars is a ****

We buy cars is a ****. I went to the Midstream branch and was assisted by Eric. He sold me a 2015 Opel Mokka. The dekra report said there is an oil leak, took the car to Opel where the previous owner took the car for servicing and at Opel I was told that the only problem with the car is the turbo. The car was overheating and now I'm stuck with a car that has more problems than the money spend on it. I paid R115000. It's a ****, I would never advice anyone to buy a car there.
