The Mercedes-Benz G-Class (G denotes Geländewagen, or off-road vehicle) was developed by the German car manufacturer during the 1970s and was developed through a partnership between Daimler-Benz and the Austrian Steyr-Daimler-Puch company. The G series cars were immediately characterized by being extremely robust, reliable and with a very good off-road capability thanks to their lay-out and the 4x4 traction. The car has been continuously improved and developed and today it is the most long-lived model of the Mercedes Benz production line up. Over the years its key design features changed very little, thereby demonstrating the worth and validity of the original design concept. One of the most successful versions was the MB G230 that gained considerable commercial success in many countries. It was also the basis for special set-ups dedicated to specific use solutions such as that dedicated to the Fire Brigade.
