Still a competent SUV after all these years, the M-Class provides solid on-road handling along with excellent all-weather capability and a safe, luxurious cabin.

2004 Highlights

Late in 2003, the ML350 replaced the ML320, meaning a larger (3.5-liter) V6 with 232 horsepower supplanted the 215-horse, 3.2-liter V6 used previously. The AMG-tuned ML55 has been discontinued, while a DVD-based navigation system is now optional for the ML350.

2004 ML500

TGI an '04,07/20/2010

It's no secret the early MLs were plagued w/problems. By '04 Merc was trying to win back consumers and my ML was a great value. All the bells and whistles, no defects, price reflected poor reputation and turned out to be a solid performer! From formal outings to hauling kids, lumber, furniture and landscape rock - still looks good as new.

I enjoy driving this car. It has a lot of power and gets around in the snow and ice really well. We bought this for our daughter 3 years ago, and we've had to replace a water pump, and the brakes, and the tires, of course...but it's dependable and zippy. Does require premium gas. It's a good little car.

My favorite vehicle in 35 years

Denver commuter,03/07/2010

I bought my '04 ML350 in june '05 with 18,000 miles on it. I commute about 50 miles per day. I've taken it on about 6 long-distance road trips too. 107,000 miles as of March '10 It is the most comfortable vehicle I've ever owned. Poor MPG (avg. 17.5). Wears out tires every 25,000 mi. Best mechanical reliability I've ever had, despite chronic "clunking" tranny on downshift from day

Don't do it!

dan_the_man1,05/25/2014

My wife and I purchased a 2004 MB 350 with 32,000 miles on it, thinking we would have a high quality vehicle for many years. We were half right. The vehicle is now ten years old and we have had one problem after another. At 52,000 miles the water pump broke. MB would not stand behind it. Shortly thereafter, we discovered the power steering was leaking. The bearing in the front wheel

Should I lease or buy a 2004 Mercedes-Benz M-Class?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
