The Mercedes M Class is a 4x4 that is as good on the road as it is off. The seven speed automatic gear box and permanent four wheel drive makes it a smooth and sure footed drive whatever the weather. With a commanding driving position and a well appointed interior the ML is a pleasure to drive on the road. When it comes to the tough stuff, the 3 ½ tinne capacity, 50cm fording depth and the ability to ascend a 45 degree slope, leaves you in no doubt that the ML is a serious bit of kit.
