Average

Excellent refinement and very composed ride quality. Quiet diesel engine. Superb cabin quality. Spacious for rear seat passengers. Capable off-road if need be.

High price. Best ride quality depends on optional air suspension. COMAND system is still frustrating to use. Four-seat accommodation only. No room for a spare wheel. Lots of reported problems with steering at low speeds.
