What Our Members Are Saying about the Seat Room and Comfort of the 2008 Mercedes-Benz M-Class

2008 Mercedes-Benz M-Class Seat Room and Comfort: Pros
YearBody/PowertrainComment
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

TrueDelta Reviews the Seat Room and Comfort of the 2015 Audi A3 / S3

2015 Audi A3 / S3 Seat Room and Comfort: Cons
YearComment
2016 Same goes for rear seat room. The Audi S3's rear seat can be a tight fit for adults, especially if those in the front seats are tall. But at least most adults will fit. My adult-sized children rode in the back seat from Detroit to Nashville and back without complaining about the amount of space. (It helped that none of us are tall; I'm 5-9.) The back seat in the CLA provides far less room for heads and legs. Mercedes markets it as a coupe for a reason. see full Audi A3 / S3 review
