The 2006 Mercedes-Benz G-Class (also known as the G-Wagen) is a luxury AWD SUV with distinct off-road prowess. Part of the first generation running since 1979 but receiving ongoing updates, it was offered in two trims: the G500 and the G55 AMG. The G500 was powered by a 5.0-liter V8 that produced 292 horsepower, while the G55 AMG had a 5.4-liter supercharged V8 delivering 469 horsepower. Both had a 5-speed automatic transmission. The G-Class boasted a robust suite of safety features, including front head airbags, dual front side-mounted airbags, and stability control. Despite its vintage design, it came with modern indulgences like navigation display, heated seats, 10-speaker Harman Kardon sound system, and other desirable tech features.
