2013 Mercedes-Benz GL Seat Room and Comfort: Pros
Year	Comment
2013	The Mercedes-Benz GL-Class is just a little longer than the Audi Q7 (201.6 vs. 200.3 inches), and isn't as wide (76.4 vs. 78.1 inches). But the Mercedes is considerably taller (72.8 vs. 68.4 inches) and not nearly as curvy. Which might explain how it is far roomier than the much sleeker Audi. Combined legroom for all three rows is 107.6 inches in the Q7 vs. 113.8 inches in the GL-Class, a large difference. The Q7's space deficit grows the farther back you sit. For adults to even fit in the Audi's third row without extreme discomfort, those in the second row must slide their seats forward to the point that they are themselves short on knee room. While the new GL350's third row sits too low to provide thigh support, it's not nearly as cramped. Further evidence that Audi didn't intend the Q7's third row for frequent use: the second-row seat doesn't do a good job of getting out of the way, making the path in and out of the way-back perhaps the tightest I've experienced. The second-row seat in the GL-Class tips forward to open up a much wider path. If manually tipping the seat is too much of a chore (perhaps because you'e a five-year-old and haven't yet learned to read this), $400 buys a power assist. But even with this option the seat must be manually returned to its upright position, so the point eludes me. see full Mercedes-Benz GL review

2006 Infiniti M Seat Room and Comfort: Pros
Year	Body/Powertrain	Comment
2007	4dr Sedan 325-horsepower 4.5L V8 5-speed shiftable automatic RWD	Very comfy, yet generally supportive. Highly adjustable with two memory options. Cooled and heated seats are wonderful. see full Infiniti M review
2006	4dr Sedan 335-horsepower 4.5L V8 5-speed shiftable automatic RWD	Most front leg room compared to similar vehicles at the time. Even rear leg room fair. First car I owned with rear view camera still working well with great color and resolution. see full Infiniti M review
