The 2013 G-Class is expected soon enough, although a small reference to the car has been leaked.
Mercedes Benz is yet to reveal a new facelift for the old fashioned and angular built G Class; however a first visual of that face lift was shown by the manufacturer when it released photographs of the new version of the GLK-Class. In one such photograph the GLK is at the forefront, while a G-Class is occupying a small space at the background standing on a cliff. After zooming in on G-Class it was found that it has a line of LED lights under the round headlights.
This is clearly a new feature for the car, as is the new assembly design of the side mirrors and relocated front fender vents. Well done to Mercedes for their ingenious leak.
