2008 Mercedes-Benz M-Class Pros and Cons at TrueDelta: Owner Pros and Cons by artcook

Ride smoothness

Self explanatory. I have the AirMatic suspension, which probably helps.

Front seat support & comfort

Bottom seat cushions are long enough for taller drivers. Padding is not too firm or too soft. Excellent support and an upright, easy-chair seating position, instead of having to extend your legs horizontally to get legroom. Results in no low back pain.

Powertrain performance

The Diesel engine is extremely smooth and climbs mountain grades with amazing ease. Getting 24-25 mpg on trips and 17-18 mpg driving around suburbia. The new EPA mileage estimates are very accurate.

Safety & braking

Actually, the brake feel is only so-so, but the overall safety, especially crash protection, is superb!

Audio & nav systems

The Harmon Kardon audio system sucks! The midrange is nasal, the highs are very harsh, and there is no real deep bass. The only bass you hear is just 80-120 Hz. boom that clouds out much of the vocals and other midrange. Going aftermarket shopping ASAP.
