This year, Mercedes-Benz is celebrating the G-Class and its 40th anniversary. It was back in February 1979 that Mercedes unveiled the 460 model series G-model for the very first time. Since that fateful unveiling, the G-Class has been a staple in the German automaker’s lineup. It has seen changes and variants over the past four decades, but the overall DNA of the model has remained the same. To celebrate, I’ve put together the different models of the G-Class that are currently for sale on duPontREGISTRY.com. Check them out below!
