High-quality materials are complemented by ample seating space in the 2009 Mercedes-Benz M-Class.
Edmunds doesn’t mince words in its appreciation of ML’s comfort and quality: “The 2009 Mercedes-Benz ML320 boasts a beautifully constructed interior, with high-quality materials virtually everywhere you look and touch. Indeed, the Benz's interior design and quality may be its most outstanding feature. Compared with the rival Lexus RX 400h, the ML320 feels (and is) thousands of dollars more expensive. Fit and finish was excellent with the exception of a slightly misaligned steering wheel cover.”
ForbesAutos states that inside the M-Class, “there’s just less than 30 cubic feet of cargo space behind the rear seats, and a touch over 72 cubic feet when they’re folded down, which is about average for this class.” Compared to the Lexus RX 350, Edmunds counters, “Passenger room is especially impressive, as the ML affords rear-seat passengers more than 39 inches of legroom—nearly 6 inches greater than the RX 350 offers.” In overall size and room, the 2009 Mercedes-Benz M-Class is more than competitive with the likes of Ford's Explorer, Jeep's Grand Cherokee, and their ilk. Its wheelbase is 114.7 inches and overall length is 188.5 inches. With the rear seats folded down, cargo volume is 72.4 cubic feet and 29.4 cubic feet with the seats upright.
Sumptuous leather seats and an air suspension add to the Mercedes-Benz M-Class's credentials as an all-day cruiser. “Cabin noise is thoroughly subdued,” Automobile.com remarks, noting the M-Class’s “richly trimmed interior, comfortable and supportive seats, and ample elbow room for five adults.” Edmunds concurs: “While there's plenty of diesel clatter outside the ML320, noise levels inside are luxury-car low at all speeds. The optional power-adjustable leather-trimmed front seats were supremely supportive, with firm bolstering that helped keep us alert on longer journeys. The backseat is nearly as inviting, boasting a chairlike seating position and ample headroom. Only passengers of above-average height will find rear legroom a bit lacking.”
