What Our Members Are Saying about the Seat Room and Comfort of the 2009 Mercedes-Benz M-Class
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.
