There's no shortage of passenger or cargo room inside the 2008 Mercedes-Benz R-Class.
This is the conclusion reached by most reviews seen at TheCarConnection.com. Cars.com reports that the Mercedes-Benz R-Class seats up to seven "courtesy of three pairs of seats [that] offer magisterial comfort and support, are wholly adjustable to suit one's physique, and remain appealing even after hours of driving." ConsumerGuide assures potential buyers that "six-footers have abundant 2nd-row headroom and knee space, plus adequate under seat foot space...seats blend fine support with soft padding." Edmunds warns that the Mercedes-Benz 2008 "new seventh-seat option, however, is a mixed bag...the extra seat does add to the R-Class' versatility, [but] encroaches on third-row knee room when in use and a too-narrow width for adult frames...it makes for a questionable addition."
Mercedes-Benz R-Class storage and cargo space is generous; ConsumerGuide reports that "second- and 3rd-row seats fold easily to lay flush with the floor, providing a cargo hold that's nearly 8 feet long," while "liftover is low for easy loading." Cars.com states "optional second-row console contains additional cupholders, and bottle holders are located in each door pocket."
Kelley Blue Book says "the interior of the 2008 Mercedes-Benz R-Class feels more like a family room than a car," due to "the panoramic sunroof that spans nearly the entire length of the vehicle." ConsumerGuide adds its "cabin design is the expected blend of rich, textured plastics, soft-touch surfaces, and high-quality materials."
Having a quiet conversation while on the road in the Mercedes-Benz R-Class is highly doable: "just a touch of driveline and road sound is evident, but the engine is nearly silent unless pushed hard," according to Cars.com, although ConsumerGuide notes that "the R320 CDI's diesel engine sounds louder here than in the E-Class sedan or M-Class SUV, with clatter that's intrusive during acceleration and noticeable at idle and in cruising."
