My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.

For buyers who crave flagship comfort and poise without the badge theatrics, the G80 serves serious luxury and refinement with a touch of surprising value — like a tuxedoed chauffeur who secretly loves great playlists.
