Love my Mercedes M Class Turbo Diesel

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.

after 3 yrs of owning the ML320 CDI, I do have a lot of problems and expenses, the check engine light never ends, the lights always have to be changed at least every 3 months, as of this time my SUV has 58000 miles and the vehicle is in and out of the dealer, cannot fix the check engine light, I already spend almost $5000 . the vehicle has been there for a good 1 month, waiting for parts, then bring it home, drive for 5 miles, check engine comes back, they change a lot of parts, the SUV also has problem with acceleration, and the engine now is so noisy when you drive it. I thought this was the best vehicle I bought, this was the worst of all the brands I have.

2008 ML320 CDI Diesel - way to go!

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!

You'd think after over 100 years in the automotive manufacturing business, Mercedes would have been able to figure out how an oil seal works but apparently not, if the ML 320 CDI is any indication. Some owners have reported oil cooler seal failure with as little as 60k miles others see it at around 100k miles but EVERYONE gets it! To fix these seals requires turbo, and intake manifold removal, for which I was given a dealer estimate of $3,700. This is after a few electronic sensor failures, in addition to a fuel pump failure that cost over $1,000 to fix (low pressure fuel pump). The dealer network is useless! The parts counter can't even tell me accurately what kind of coolant I'm supposed to use. It originally came with yellow, then they switched... But to what? The forums say blue colored coolant but the dealership tried to sell me red?!?!?! The whole reason why I bought this car was to offer my wife years of care-free driving. That has not been our experience. The vehicle looks and drives well but it is frustrating to own at times.

Go diesel!

This is a great SUV all-around, but the diesel clinched it for me. It just makes so much sense for trucks and SUVs. Yes, it's a hair louder than a gas engine under acceleration (which is excellent, by the way, because of all that torque). But cruising is very quiet, and there's absolutely no smoke or odor, ever. Bottom line: you get the space and utility you need at a thrifty 26 mpg. Plus, you can feel good about being green with the smaller carbon footprint. Really, you've got to try one.
