Review of the 2008 Mercedes-Benz M-Class

  • The 2008 Mercedes-Benz M-Class should make a fine choice for shoppers desiring SUV versatility along with the traditional Mercedes traits of quality, prestige and safety.

  • Safety
  • Pros

    A wide range of engines, comfortable for five, sure-footed in bad weather, high-quality interior materials and construction.

  • Cons

    Regular V6 is short on low-end torque, no third-row seat option, expensive for its segment, antiquated electronics interface.

  • What's New for 2008

    The 2008 Mercedes-Benz M-Class sees additions to its standard and optional packages' features lists. Minimal visual changes include newly standard chrome accents (grille, door handles and exhaust tips) that spice up the looks of this year's ML. Last year's ML500 model has been replaced by the ML550 -- the number change signifies a new 5.5-liter V8. It provides 80 more horsepower than the ML500's V8. The ML350 "Edition 10" celebrates the 10th anniversary of the M-Class with special exterior and interior trim, as well as a few more luxury features.

Very nice

Vehicle: 2008 Mercedes-Benz M-Class ML550 4dr SUV AWD (5.5L 8cyl 7A)

We have one without the airmatic setupů.Lightens the weight of the ML and eliminates any potential air springs issues in the future. It has blazing acceleration - when launched, even at part throttle, it can feel like you just got rear ended by a truck that forgot to stop. You'd have to see it to believe what cars it can out accelerate on a regular basis. Has a solid yet comfortable ride. Structure is very solid & tough. Engine & exhaust are tuned to be quiet & relaxed, and so don't be expecting high performance sounds. Has been very reliable so far. It's also a very safe SUV with great crash test results. MPG is actually not bad considering this level of power in an SUV package.

Bad dealership bad car

by on
Vehicle: 2008 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)

This is the bottom line worst car I have ever purchased and the dealership is even worse than the car. I purchased an ML350, 5 days after I purchased the car it had to go in for service and in less than 20 months the car has been in 21 times! Everything from the rear hatch not working (constant problem), sunroof, cam shafts leaking, oil leaking, random lights not working, battery going dead for no reason and stranding me, and the last one was the a/c going out completely. Of course out of 21 times in the dealership my service advisor who is the only decent part of this experience does not know what to do except to schedule me for service for next month in advance because she knows soon so

Probably not worth the investment

by on
Vehicle: 2008 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)

I bought this car new in October 2007. I have general dislikes about this vehicle and the cost of ownership. First, the SUV has 37k miles on it and I am on my 3rd set of tires at $1100 per set (including mounting and balancing). MBUSA says it's due to the weight of the vehicle and that the tires available are soft (whatever you do DO NOT buy Continental 4X4 contacts for this car). Second, there are many, many little things that for a MB are un acceptable like, front defroster only has one setting, which is high, then you need to play the on/off game with it when the windows fog up, the radio does not display the song or artist, the alarm makes no audio sound to indicate it is alarmed, ect

Update after two years of

Vehicle: 2008 Mercedes-Benz M-Class ML550 4dr SUV AWD (5.5L 8cyl 7A)

I have now had my ML550 two years since my last review. I actually enjoy my vehicle even more than before!! I have had no problems with it and the power is just so amazing with the gas mileage not so bad (avg 15mpg). I live downtown and do not drive a lot of hwy miles but when on hwy I get 19 to 20 mpg. Small trucks with V6 engines do not get better in town gas mpg. The quality has stood up and I intend to keep this ML550 for a long time! I just love this SUV!!

Proud owner of ml 350

Vehicle: 2008 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)

Back in 2008, I test drove Volvo, BMW, Audi, Acura. Finally I chose ML350. I believe in my life I have always made wrong decisions, but I have never regretted my ML350 purchase. Then I bought Audi Q7 2010 for my wife, but somehow it has failed to gain my loyalty. Even after 60,000 miles my MB drives like a newborn. Amazing SUV.

Stranded

Vehicle: 2008 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)

I have only had my ML350 for 1 year and the battery has died on me twice already. Here I am in a brand new Mercedes and I have to get a jump, how embarrasing. The second time the battery died I took it to the dealership and they said that the computer chip got wet some how. They want to charge me $900, but it's not happening.

Full 2008 Mercedes-Benz M-Class Review

What's New for 2008

The 2008 Mercedes-Benz M-Class sees additions to its standard and optional packages' features lists. Minimal visual changes include newly standard chrome accents (grille, door handles and exhaust tips) that spice up the looks of this year's ML. Last year's ML500 model has been replaced by the ML550 -- the number change signifies a new 5.5-liter V8. It provides 80 more horsepower than the ML500's V8. The ML350 "Edition 10" celebrates the 10th anniversary of the M-Class with special exterior and interior trim, as well as a few more luxury features.

Introduction

With so many premium-badged luxury SUVs available now, it's easy to forget that just 10 years ago Mercedes-Benz was one of the first with its M-Class. The original, truck-based (body-on-frame) M-Class was a strong seller for the brand, despite a number of early build quality issues related to its new U.S.-based production. A few years ago the second-generation model debuted. Evidently realizing that about the same number of people who actually use their home fitness machines use their SUVs to go off-road, Mercedes gave the new ML (officially now referred to as the M-Class) a carlike unit-body architecture and a revised suspension design that brought a more on-road-biased personality to this premium sport-utility. In addition to improved handling and ride qualities, the second-generation ML received more aggressive styling, higher-quality cabin fitments and new engines.

The M-Class rolls into 2008 with mostly detail changes that include a celebration of its 10th birthday. Mercedes offers the widest array of power plants in the segment, from a fuel-stretching diesel in the ML320 CDI to a supercar-worthy 507-hp V8 in the ML63 AMG. There's also a new mainstream V8 this year. Found in the ML550 model, this latest-generation 5.5-liter V8 cranks out 382 hp -- 80 more than the 5.0-liter V8 found in last year's ML500. The rise in power hasn't come at the expense of fuel economy, either, with the ML500 and ML550 having very similar EPA estimates.

The new engine is welcome, but the 2008 Mercedes-Benz M-Class faces some serious competition in the $50,000 luxury midsize SUV segment. It's not the only fresh-faced ute on the block, as the Acura MDX, Audi Q7 and BMW X5 were all- new or redesigned just last year, and the Porsche Cayenne and Volkswagen Touareg 2 have been heavily revised for 2008. The advantage of the M-Class is that it offers what most folks typically buy Mercedes-Benzes for: a vaultlike feeling of quality and luxury, visible prestige and state-of-the-art safety. What it doesn't offer is a third-row seat. But one can always consider its stablemate, the larger GL-Class, if the ability to carry up to seven passengers is a must.

Body Styles, Trim Levels, and Options

The 2008 Mercedes-Benz M-Class is a midsize, five-passenger luxury SUV. Four trim levels are offered: ML350, ML320 CDI, ML550 and ML63 AMG. The ML350 and 320 CDI are identically equipped with 19-inch wheels, a sunroof, TeleAid, dual-zone automatic climate control, power front seats, maple wood interior trim and a CD player with an auxiliary audio jack. To celebrate the ML's 10th birthday, there will be the ML350 Edition 10, which comes in either black or white and features split-spoke wheels, tinted headlight and taillight bezels, a two-tone leather interior with birch wood and aluminum accents, heated seats, a CD changer and the obligatory "Edition 10" floor mats and exterior badges.

To the regular ML350, the ML550 adds AMG-style bumpers and (19-inch) wheels, running boards and heated front seats. The ML63 AMG features special interior and exterior styling details, as well as a sport-tuned air suspension, 20-inch wheels, upgraded brakes, active headlights, corner-illuminating foglights and ultra-supportive sport seats.

For all but the ML63, there are many options, most grouped in expensive packages. Feature highlights include an adjustable air suspension, park assist, adaptive cruise control, adaptive xenon HID headlights, leather upholstery, a navigation system with a rearview camera, a rear-seat entertainment system and a Harman Kardon Logic7 surround-sound audio system with satellite radio. Upgraded front seats with driver memory, heated front and rear seats, tri-zone climate control, a sunroof and a power liftgate are also available.

Powertrains and Performance

A variety of engines are available for the 2008 M-Class. The ML320 CDI has a 3.0-liter turbodiesel rated at 215 hp and a stout 398 pound-feet of torque. Being a diesel, it provides better fuel mileage (rated at 18 mpg city and 24 mpg highway) and range (more than 600 miles) than a comparably sized gasoline engine. Note that due to stricter emissions standards, the ML320 is unavailable in California-level emission states. The ML350 has a 3.5-liter V6 that makes 268 hp and 258 lb-ft of torque.

Offering brisk performance, the ML550 boasts a 5.5-liter V8 that pumps out 382 hp and 391 lb-ft of torque. Should that not be enough, there is the ML63 AMG with a 6.3-liter V8 making a stunning 503 hp and 465 lb-ft of torque. That's enough to propel this SUV from zero to 60 mph in just 4.7 seconds. All models are fitted with a seven-speed automatic transmission and all-wheel drive. Maximum tow capacity when properly equipped is 5,000 pounds.

Safety

Antilock disc brakes with brake assist, traction and stability control, hill descent/ascent control and a full complement of airbags (front seat side and full-length side curtain) are all standard. In government crash tests, the 2008 Mercedes-Benz M-Class posted perfect five-star scores in both frontal- and side-impact testing. The Insurance Institute for Highway Safety gave the SUV a top score of "Good" for its protection of occupants in frontal-offset crashes.

Interior Design and Special Features

Generous fillets of bird's eye maple wood and brushed aluminum trim lend the cabin a warm, upscale ambiance. Large front cupholders and adequate storage cubbies come in handy on road trips. 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. Folding down the rear seat provides a maximum 72 cubic feet of cargo room, which is on the small side for the segment.

Driving Impressions

Although the 2008 Mercedes ML's steering is precise, it doesn't offer much feedback and feels a little dead in the center. The brakes, however, offer a sure-footed pedal and stop this SUV quickly. Despite some body roll, the near 5,000-pound, all-wheel-drive ML is a predictable and stable handler. It offers a confident feel during inclement weather as well as when negotiating twisty mountain roads on the way to the hiking or mountain biking trailhead.

Probably even less than that. My lease on the 2006 M class is coming up on expiration in August and I had an allowance of 12k miles/yr and after 2 years have a total of only 9000 miles on it! I guess?...
