TheCarConnection.com notes that despite overall satisfaction with interior comfort and quality, the 2008 Infiniti EX35 is a bit short on room. This impression is confirmed at Car and Driver, which describes this vehicle as "heavier on sport than utility."
AutoWeek says, “It features high-quality materials and superbly comfortable seats,” but most reviews from across the Web noted that the 2008 Infiniti EX35 has a small backseat. “The EX35's greatest interior shortcoming is the size of its backseat,” Cars.com says, “which is especially frustrating, because the lack of space seems unnecessary.” Motor Trend points out that compared to the Acura RDX, “Rear-seat legroom, at 28.5 inches, pales to the 37.7 in the RDX, and the meager 16.8 cubic feet of cargo volume (only 3.3 more than that of a G35) is down by a couple of Miata trunks compared with the Acura's 27.8.”
As far as materials are concerned, Cars.com mentions that "aluminum trim appears sparingly and is effective, as is the black-lacquer bezel on the center console and control panel." These are standard in the base model of the 2008 Infiniti EX35, but Edmunds reports that "the optional maple wood trim is much nicer." This source also comments that "interior materials aren't going to win any awards for quality," but those who are willing to pay extra can have genuine leather upholstery.
Other than that, Edmunds reports "solid ergonomics" all around. AutoWeek “found the interior extremely pleasant. It features high-quality materials and superbly comfortable seats.”
Cars.com appears to disagree with Edmunds on the quality issue: "The interior is appointed like other Infiniti models... with modern, high-quality materials." This source does, however, elaborate on the ergonomic features, which include a manual tilt/telescoping steering wheel and power lumbar adjustment for the seats. It should be noted, however, that these are not included on the base model.
