Buyer’s Guide Anthony Zelenyuk A friendly warning to all motorists looking into buying a Mercedes Benz. The MB GL has a hidden defect / characteristic which is not disclosed to you when buying but which you will discover later when driving the car. Three months ago I bought a brand new GL350 BLUETEC. The vehicle price was R1.1 million. After driving less than 500 km, I discovered a vibration in the body at highway speeds (100 – 120 km/h). The car has been back to the dealer countless times over the last 3 months, and I spent a huge amount of time and effort in trying to get somebody at Mercedes Benz to do something about it. Their unashamed and comical final answer is that the vibration is “normal” and caused by the road surface (on a top of the range luxury SUV with air suspension)! FYI all tests were done on the N1 in Centurion area – probably one of the best and smoothest roads in SA. In essence they have told me to get lost. Furthermore, this seems to be a much wider problem. See this MB owner’s forum: http://mbworld.org/forums/gl-class-x166/499455-vibration-problem-new-gl550.html I have driven many other vehicles over many years on the same roads, including SUV’s like Q7, Cayenne, Lexus RX, and have never experienced any problems whatsoever.
