"Mercedes-Benz's mammoth SUV is being facelifted for its mid-lifecycle. The GL-Class was launched in 2006. It seems Mercedes-Benz is offering two different trim levels of the GL in the same way as the new 2010 E-Class. These spied prototypes show the black car with an LED light strip on the front bumper and a newly designed stainless steel underbody guard. That one would be the Elegance. The silver vehicle should be the Avantgarde model with its twin round headlights taken from the 2010 E-Class Avantgarde version."
