Best SUV ever!

2008 Mercedes-Benz M-Class Diesel ML320 CDI 4dr SUV AWD (3.0L 6cyl Turbodiesel 7A)

Review

I ordered this car with all available options. Towing my horses on highways and hills is effortless and I have NEVER gotten less than 20mpg. I find the nav system very accurate but data entry is a pain. The Airmatic suspension makes a HUGE difference in the ride and handling quality over lesser-equipped M Class cars. There have been zero defects, so my only expense has been to replace the tires and 3 maintenance stops. An outstanding vehicle made in the USA!

Why do hybrids even exist?

Review

Wonderful vehicle. Terrific performance from all that diesel torque, yet it gets superb mileage (avg. 22.1 MPG over 45,000 miles). Very comfortable on long trips. Lots of storage. However, it's outrageous that memory seats are not standard equipment at this price. Maybe they are now standard on newer models? My dealer in Grand Rapids, Michigan is excellent, both sales and service. BTW, hybrids are a losing proposition. We already have diesel infrastructure in place, the technology is proven beyond a shadow of a doubt and the diesel complaints (noise, polution and smell) have been solved. My second M-B diesel won't be my last.

Nice car but many little problems.

Review

The dealership is excellent and does its best, but my car had a battery drain problem that left me stranded in airport parking lots several times after long trips from Europe and Asia. After many interventions and, as long as a week at the dealership at a time, to check it out, they changed the battery. I suspect once the battery gets old it will discharge again but I only have a few months left on the lease. The car also has had small problems that should not appear on a 55K plus car.

A good Mercedes Diesel

Review

SUV is more than we expected. Good driving experience, excellent mileage @ 30 mpg highway and 25 in town. Radio and MB tech pkg helpful. HD lights a must, XM radio and NAV work well. Seats comfortable even with MB Tex. Would definitely buy again. No problems so far in this nearly 2-year- old MB Diesel SUV. Bought the extended warranty to 100K miles.

Destroys Tires
By Edward Vinca on 06/29/09 08:18 AM (PDT)

Review

After 17,000 miles, tires developed excessive thumping. After a couple of conversations with the dealer, the dealer, as a favor, agreed to replace the tires, but I was responsible for the four wheel alignment. After 11,000 miles on the second set of tires, the thumping came back. Dealership agreed to check the alignment. According to them, it was within specs. They told me to talk to Michelin Tires. Michelin agreed to replace the tires as a favor. However, they are no longer responsible for wearing of the tires. So at this point, the car having 28,000 miles, the third set of tires has been put on. Mercedes will not accept this problem as their responsibility. HELP!

Good SUV

Review

Bought this vehicle new and have been impressed with the handling and the fuel mileage. No one even guesses that this is a diesel when they are riding in it. One of the best features is the locomotive like pull while merging onto the interstate. Absolutely no problems finding diesel and with the large tank you cover a lot of distance. 27mpg in mixed driving.

Exactly what I expected

Review

It's no RR Sport. Not as fun- but 27.4mpg hwy and between 20-22 overall. The gas mileage is great and less carbon emissions. Diesel engine noise is annoying. Porsche will win if they can combine sport and "green" in the new Cayenne!

2008 ML320 CDI Diesel - way to go!

Review

Bought the ML320 CDI after much consideration vs the BMW X5. It is better than advertised on MPG! I get 24- 28MPG around town and 30-32MPG on the hiway! Minimum 600 - 700 miles per tankfull! Plenty of power and torque that no gas engine can match! No black smoke and no noise! Americans should re-educate themselves about diesel! No hybrid can match the power and range - period. It is way ahead of any competitor in this range and I am 100% satisfied and as a previous Mercedes Benz owner - this the best I ever had!

Diesel SUV that drives like a sports car

It is really fun to drive! This is unusual for an SUV (especially for a Diesel). The engine gives good low and mid range power and acceleration and is smooth and quiet. The mileage has been better than advertised. The iPod integration is nice.

Love my Mercedes M Class Turbo Diesel

Review

Sold my '03 BMW X5 and purchased my ML 320CDI in Jan '08. I was torn between the Mercedes and the new BMW X5 but chose the ML based on good looks, power and fun to drive. I find I just want to get in the car and drive. The SUV is smooth, quiet, luxurious and most of all great fun to drive. Terrific sound system. Average 22 mpg combined city/highway. No problems since I purchased it. Would highly recommend.
