Most vehicles need replacing every few years, but not the
Mercedes-Benz G-Class. It's been refined over the years, but the SUV available today is essentially the same as it was at its introduction 1979. That's before most of us were born, yet the Gelandewagen soldiers on. Mercedes tried to replace it in 2006 with the more modern GL-Class, but demand saw the original continue right alongside. By now the G-Class is so hopelessly behind that Benz is going to have to replace it in order to keep it ahead of the regulations. But that won't be easy.
