I purchased my 5th Mercedes Benz, from Shiraz Auto in Lenz. I have always been an avid Mercedes Benz fan and purchase the brand, for the service, quality and overall "reliability". Firstly the service at the dealership was atrocious. The salesmen, who I have dealt with on numerous occasions, was rude and extremely disrespectful, I received an incorrectly spec'd car which differed vastly in the quoted price, after waiting for 6 months, after placing the order. Irrespective I commenced with the purchase of the vehicle in October 2015 (Brand New). Windows were tinted, quality was not up to standard and to date not been rectified, after numerous discussions. While driving in February 2016 (4 months @ 8000km's) the car stalled and all electronics including the accelerator became unresponsive. All dash warning lights lit up without a specific indication of the problem and car refused to start. The Mercedes roadside assistance was surprisingly fast to respond, however the technician had no clue what was wrong with the car... "as usual"! Car was towed to Mercedes Benz Northcliff and 2 months later, I am still paying a premium and insurance for a car which I do not have in my possession. I am told that various engine parts, from the pistons, to the piston rings need to be replaced. Ideally one purchases a new vehicle, especially a brand like Mercedes for reliability and Quality. My car needs to be replaced and service and responsiveness needs to dramatically improve, as this is tarnishing the brand name and image!!!
