2013 Mercedes-Benz GLK-Class Reviews - The beginning of 2012 marked another milestone for the SUV models from Mercedes-Benz. From the market launch of the G-Class 33 years ago until the end of 2011, over two million models were delivered to customers. The SUVs account for around one fifth of Mercedes-Benz's global sales. The USA is by far the largest market for the entire SUV family, including the M-Class, the GLK and the GL-Class. The second-largest market for off-road vehicles as a whole is China, followed by Germany. The G-Class off-road classics are the most popular choice on the domestic market in Germany, while the R-Class enjoys the strongest demand in China.
