Mercedes ML 320 CDI 4Matic 2007 review.

I recently acquired a vehicle from Value Auto and this is a brief description of my experience. I saw the vehicle, a Mercedes ML 320 CDI 4Matic 2007 on the internet on Gumtree. I liked what I saw and contacted the seller namely Riaan Langeveldt. He informed me that to his knowledge that the vehicle are in good shape for its year model. I paid a holding deposit and a roadworthy fee of R1000 on EFT and flew down to Cape town where I was met by George. I took delivery of the vehicle and drove off to the fuel pump 20m away. After refueling the car would not start, battery dead. George gave me a jumpstart assuring me its because the vehicle was standing for a while not driven. I noticed that the rear right brake light where not working. Again George said probably a defective bulb. Taking to mind , I was given a full roadworthy, brake light , reverse light and indicator lamp not working. When arriving in Stillbaai I had to replace the battery for it was completely dead. While driving the brakes was not good. It was shuddering and shaking the steering wheel , again was this roadworthy ? Both front and rear disc brakes badly worn beyond safety measurements. When I returned home to Pretoria at the end of the week, I discovered the reason the brake light was not working. The globe was removed to hide the fact that it was staying on all the time. A closer inspection I discovered that the rear SAM computer had water damage and the indicator, reverse lamp and brake light was affected. Again , was this roadworthy ? I called George who told me he would talk to his partner Riaan Langeveldt and come back to me. This never happened. Later I WhatsApped him about the navigation DVD for the vehicle, he never even rep****. To list just a few issues, the broken grill was tied with cableties. Sure this is a old vehicle, but with roadworthy issues after I paid R1000 for a full roadworthy. You decide if this is the experience you want if you buy . I would not go there again.
