The 2012 Mercedes-Benz M-Class is a mid-size luxury SUV that offers an excellent mix of comfort, utility and power, all with the prestige inherent in any vehicle adorned with the Three-Pointed Star. With its range of engine choices and package options, the M-Class can take the form of a midlevel people mover that competes with the Lexus RX and BMW X5, to a super-premium hauler that can go toe-to-toe with a Range Rover Sport or Porsche Cayenne Turbo.
Whether you want to tackle any road in sublime comfort or hit up to 174 mph on the autobahn, the M-Class can do it. On a more pragmatic front, the Mercedes M-Class boasts reams of safety features, great cargo space, and the ability to tow up to 7,200 pounds.
The Mercedes-Benz M-Class has been revamped for the 2012 model year, which marks its third generation since debuting in 1998. The 2012 M-Class has slightly bigger exterior dimensions and a sleeker design, upgraded interior and tech features, standard all-wheel drive, a new 7-speed automatic transmission, and V6 and V8 engines that are more powerful yet drink less fuel. The hybrid version has been dropped but the stout and efficient BlueTEC diesel remains.
Driving Impressions The M-Class further dashes the notion that ride quality must be sacrificed to have a high-riding, all-wheel-drive machine that can tackle just about any terrain. The 2012 Mercedes-Benz M-Class can...tame the hazards of ruts, snow and muck – not to mention rush-hour traffic and speed bumps – while treating its driver and passengers to a supple travel experience. The M-Class doesn't feel quite as sporty as its BMW rivals, but it's anything but slow, especially when equipped with a V8 engine. For those who do want a more dynamic driving experience, that can be had with the touch of a button that adjusts the suspension. We preferred to leave the "comfort" setting on to take advantage of this SUV's soft ride. Even at freeway speeds, the cabin is remarkably hushed. Visibility is good, but we still recommend the optional blind-spot monitoring system. Steering feels a tad light at lower speeds and isn't very communicative overall. The M-Class has a relatively tight turning radius of 38.7 feet, which means fewer 3-point turns.
This feature is a lifesaver when your hands are filled with groceries. Just touch a button on the key fob and the tailgate lifts. Closing is equally simple, either via a button on the door itself or with another press on the key fob.
Fold and Tumble Rear Seats
Folding rear seats are ubiquitous, but not so those that tumble forward, too. Though it takes an extra step, the setup yields a flat floor that is better for carrying cargo.
The 2012 M-Class has all the soft-touch materials, wood accents, and sea of sturdy buttons and knobs you'd expect in a luxury vehicle. Leather seating will still cost you extra, but even the base "MB-Tex" vinyl provides an appreciable amount of comfort and good textile feel. That sensation carries over to just about every other component, from the available wood steering wheel to the tiny gear selector, which bucks the trend not just with its size but by being mounted on the steering-wheel column instead of the center console. Rear passengers are treated to ample legroom, reclining seats, and movies of their choice with the optional twin LCD screens mounted inside the front-seat headrests.Exterior
With the 2012 model comes a significant freshening of the M-Class' sheetmetal. Up front is a revised grille that emphasizes the Mercedes-Benz emblem, and sleeker headlights that give the M-Class a more athletic look. Adding to the sportier appearance is a sculpted beltline running the sides. The rear benefits from a squatter appearance and taillights that are stretched horizontally, which gives the 2012 M-Class a more sporting vs. utilitarian look. The high-performance ML63 AMG models are distinguished by a larger air intake up front, wider front fenders and quad tailpipes in back.
All 2012 Mercedes-Benz M-Class SUVs come with all-wheel drive, a 7-speed automatic transmission, power sunroof, 8-way heated front seats, power liftgate, dual-zone automatic climate control, a 7-inch color center display, and an 8-speaker AM/FM/CD/DVD audio system with weather band and HD Radio. Safety features include nine airbags and Mercedes' Attention Assist system that monitors for driver drowsiness. ML350 and ML550 versions ride on big, 19-inch wheels, while the top-line ML63 AMG rolls on 20-inchers.
Here's where the M-Class' $50,000 base price can quickly inflate by thousands of dollars. Many options are bundled into packages and include navigation, rear-view camera, blind-spot monitoring, adaptive cruise control, and a premium harman/kardon surround-sound system. Further options include a panorama roof, heated steering wheel, heated rear seats and the Parktronic system to aid with parallel parking. The $5,000-plus Dynamic Handling Package makes for a more sporting M-Class with the addition of 20-inch wheels, air suspension and an adaptive damping system. Buyers of the AMG performance version who find its 518 horsepower still inadequate can opt for a package that adds another 32 hp and brings the SUV's top speed to 174 mph.
Each of the four 2012 M-Class models is distinguished by its own engine. At the lowest-priced end is the ML350 with a still-robust V6. Next is the most fuel-efficient of the bunch, the ML350 BlueTEC with a V6 turbodiesel that puts out tremendous power yet yields up to 27 mpg on the highway and a stated cruising range of more than 600 miles. The diesel is 50-state legal and of the "clean" variety, meaning it doesn't put out the nasty emissions of past diesels, but will require injections of the urea-based AdBlue fluid throughout its life. The ML550 SUV uses a powerful-but-fuel-thirsty V8 biturbo, and the ML63 AMG uses an even bigger, more powerful – and even less fuel-efficient – V8. Even the "slowest" M-Class can hit 60 mph in just over seven seconds, while the AMG version can do it in 4.7 seconds, on par with high-performance sports cars.

Pros: "Brand Prestige"
Cons: "Overpriced truck, under-powered V6 engine"
Likely to recommend this car? (1-10): 3
"Driving dynamics is similar to Grand Cherokee due to virtually identical chassis and body frame. The under-powered V6 engine is simply too weak to move briskly this 5000 lbs truck. I should have bought the V8 which will definitely change my poor driving experience. As to the driving position and seating comfort, it is about average, and not the command view that an SUV is supposed to have (Lexus GX has an elevated and upright driving position that other luxury SUVs ought to have). This SUV is overpriced by at least 5K even if MB has great brand prestige. And too bad, all those European or Japanese luxury SUVs are overpriced trucks that are only worth about 70% of their MSRP when new. But that does not mean Detroit luxury SUVs are bargains. Instead, Detroit luxury SUVs are a joke in terms of quality and reliability whether they are 2004 models or 2014 models."

"Just bought the ML350 Bluetec 2014. Was a little anxous because of some of the negative reviews out there. However I am glad I stuck with my instict after test driving the car. It is a really nice car! Very quiet, smooth, and comfortable. The interior is nice and the diesel engine is just phenomenal. It starts slow but boy it catches up with the torque like a hot knife in butter. Also for a Diesel it is very quiet and had no problem starting in -10 degree weather. It is like having the power of a V8 engine and the fuel economy of V4. Cant beat it. Interior is very nice. Connectivity to bluetooth is very seamless and command system is very good though could be better. The only gripe I have is that not all diesel gas stations carry the B5 diesel(higher Biodiesel content clogs the filter and voids your warranty) which MB dealers dont tell you up front. However, I can live with that. Overall it is a very comfortable and elegant ride. if you are looking for sporty ride look at Porsche Cayenne. Though it is very expensive with the add ons compared to the ML. Test Drove BMW X5 too which is also nice but the interior feels cramped. Diesel ML was hands down the winner when I look at the whole package."

"Tested BMW, Lexus, Infinity, Audi, and Cadillac, gas engine all. Only the BMW could comparefavorably. Both more pricy than the others with same features, Leather not standard in either, but I actually prefer the leatherete, since it is more durable . ML performance equal to BMW, but ML won the day because I preferred the interior far better, especially having the shift contols on the steering column, allow more space for storage and beverages."

Pros: "Exterior Design, Cargo space, Interior room"
Likely to recommend this car? (1-10): 1
"I leased this vehicle in December 2012 and it's been a disaster: 1) Car "clanks" when you start it. Mercedes pretty much had to rebuild the motor to get it to stop doing it. They said it was a "known" problem without a fix. It wasn't until I threatened them with the Texas Lemon law that they actually fixed the problem. My wife's E350 convertible has the same problem. 2) AC smells like body odor. They did a "complimentary" $250 treatment on the car to get rid of the smell. It still smells and Park Place Motor Cars in Dallas still can't resolve the problem. 3) Transmission is doing double down-shifts. When breaking or taking your foot of the gas the transmission lurches you forward. Park Place still unable to fix it. 4) Passenger and Driver seats move slightly on turns, which is incredibly annoying. Park Place still unable to fix it. I'm following through with Lemon Paperwork on this vehicle. Stay away!"

Pros: "Fun to drive, turbo V8 power, quiet, refined inter"
Cons: "Rear wiper switch"
Likely to recommend this car? (1-10): 10
"I have the ML550, the V8, after a 2008 and 2010 ML 350. I love this car. The interior is more E-class, whereas the previous generation was more C-class. The sound of the parking brake release, turn signals, door locks -- all very refined and quieter. Graphics, both instrument cluster and COMAND, much improved and incredibly sharp. Quiet on the road, good ride and handling. The twin turbo V8 is a blast! My only complaint -- it's very hard to get a single swipe of the rear wiper the way the switch is configured. I've owned 3 German Mercedes (2 E-class, 1 CLK) and the MLs absolutely beat them in quality."
