Although noise can be intrusive, the 2009 Infiniti M's cabin features rich materials such as real wood or metal trim and, for the most part, comfortable seating.
"A warm, upscale ambiance" is how ConsumerGuide describes the Infiniti M's cabin. However, Edmunds warns, "the quality of materials is a bit uneven, and we find that the layout of the center stack controls isn't as clean and intuitive as it could be." Cars.com notes, "There are leather wrappings around the door pulls and chrome runners along the steering wheel."
ConsumerGuide finds that noise is a problem in this Infiniti, saying the 2009 M35X and M45 "thump more loudly over cracks and bumps.” Edmunds reports, "It is somewhat less peaceful than other performance luxury cruisers,” and “at highway speeds, the Infiniti M35 also exhibits a noticeable amount of engine and road noise."
Cars.com notes of the 2009 Infiniti M, "Four of the five M's seats offer ample legroom and headroom, but the bulky floor hump in back means a fifth passenger has to share foot room." They like the fact that "after you park, the steering wheel automatically powers upward to ease exit and entry—and does so much faster than in some of the M's crankier peers." Infiniti 2009 Ms have 105.2 cubic feet of cabin volume, also according to Cars.com.
"The Infiniti M35's large cabin seats five comfortably and is well appointed with leather trim and standard rosewood accents. Its seats are firm, highly adjustable and comfortably bolstered," reports Edmunds. They like the Infiniti M's "10-way power and climate-controlled seats" and detail optional features: "power reclining and heated rear seats, rear audio controls, and a rear sunshade."
"Interior storage is OK," says ConsumerGuide of the 2009 Infiniti M. "[There's] good trunk volume and lid hinges don't intrude, but short aperture means drawer-like access." Kelley Blue Book points out "a pull-down center armrest [in the rear] conceals a modest pass-through opening to the M's 14.9 cubic-foot trunk."
