2009 Mercedes-Benz M-Class Seat Room and Comfort: Pros
Year	Body/Powertrain	Comment
2008	4dr SUV turbocharged 215hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	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. see full Mercedes-Benz M-Class review
