Dishonest and unreliable!!!

We bought a 2011 BMW 320i from them. The first time I started the vehicle the oil warning came on. Take note: we did not have any warnings when the vehicle was test driven by a friend. I had to put in 8pints of oil... for the day. The 3rd day, the red warning light came on.. there were warning lights for lights malfunction, oil level, boot open (although it was closed) and this after they said there was nothing wrong. Took the car for a diagnostic an oh my soul... was there problems...to the value of another R50 000.00 / R60 000.00. The car is now standing to be fixed and costing us extra!! DO NOT BUY FROM THEM!! I REPEAT.... DO NOT BUY A VEHICLE FROM THEM!!
