The 2009 Porsche 911 lineup is, by the accounts of a wide range of review sources, quite comfortable up front and well built, but essentially useless for passengers who try to use the backseat.
Edmunds claims that "large footwells and a tilt/telescoping steering column virtually guarantee that most drivers will be comfortable behind the wheel," but they also note of the backseats that "in a pinch, they'll work for small children, but no more than that." Up front, "room is good" and the "911's seats hug without binding and are long-haul supportive," says ConsumerGuide. For extra comfort and support, reports Forbes Autos, Porsche 911 customers have the option of upgrading to Adaptive Sport Seats, which "improve both lateral support and overall comfort." Cars.com finds that although they are "called four-passenger automobiles by Porsche, 911s have plenty of space for front-seat occupants, but backseat riders are in for a major squeeze."
Thanks to the rear-engine layout of the Porsche 911, the underhood storage compartment is free to hold "a couple of gym bags," according to ConsumerGuide, which also declares that overall cargo room is "great for a sports car." Inside the cabin, even the lightweight 911 Porsche GT2 retains "two swing-arm cup holders," which are present on all 2009 Porsche 911 models. Forbes Autos claims that "the Porsche 911 Targa provides a surprising amount of cargo flexibility," due in part to the fact that "the rear seats fold forward to create a flat cargo floor" and the "lift-up glass hatch makes accessing this space much easier than on other 911 coupes." Edmunds reports that although the folding rear seats provide some storage space, "the 911's principal cargo area is located underneath the hood up front."
ConsumerGuide recognizes the quality that comes with the Porsche badge, saying that "you pay plenty, but that's partly offset by solid construction." ConsumerGuide adds that "cabin materials are solid and mostly upscale," while Motor Trend raves about the standard "rich Alcantara" that adorns the interior of the GT2 and GT3 variants of the 911 Porsche. Forbes Autos points out that "Porsche 911s are usually completely devoid of creaks and rattles," though they notice "creaks when going over potholes" in their Porsche 911 Targa. Otherwise, they praise "plenty of engineering forethought" that goes into every 911 Porsche.
One complaint lodged by Automobile Magazine comes from testing the 2009 Porsche 911 Turbo Cabriolet; they state that "when the turbos are on full boost, intake honk and turbo whoosh create a giant sucking sound that assaults your ears." Otherwise, most reviewers agree with ConsumerGuide when they say that there is "lots of engine and tire noise, but 911s are on par for ultra-performance sports cars." ConsumerGuide considers the ambient noise within the cabin to be "music to an enthusiast's ears,” because it mostly comes from "the engine's unique sound.”
Another area of concern on the 911 Porsche Targa models is the retractable roof, which Forbes Autos notes "reduces what little rear-seat headroom there is to begin with and could even smack a rear occupant in the head." It is also worth mentioning that both the GT3 and GT2 variants of the 911 Porsche do away with the rear seats altogether, in the interest of cutting weight.
