"Purchased my 2001 ML320 new and had all maintenance done on schedule at dealership. Loved the car, the ride, everything. But once it fell out of warranty had all the named problems: fuel sensors, window regulators, brakes, brakes, brakes, engine light, broken arm on moonroof. Traded in because I was fearful of the electrical diagnostic and costs. Every time I see one, I want to get another, but just leary of maintenance issues. Also, like another reviewer comment, service guy at dealership said he'd never own an M Class because of issues he sees everyday. Got Acura MDX reliable as the day is long, but a much bigger vehicle."
"We bought our ML500 new in 2002. Please, if you're looking at pre-owned ML's & think you need the navigation system...think again. We have it, and it is so slow & unreliable. You literally have to be less than a block away for it to work. It is so inefficient! Really frustrating, especially when you are lost & need the navigation system in a hurry. Also, the "check engine" light is obnoxious! Maintenance costs are too high, and resale value is pathetic. The 500 is sporty, and has a lot of power. Good looking, and has been pretty reliable in the 5+ years of ownership...but JUST SAY NO TO THE NAVIGATION!!"
"I HAVE OWNED THIS CAR SINCE 2008 AND BOUGHT IT WITH 80,000 MILES ON IT. I HAVE REPAIRED A FEW THINGS LIKE 2 OXYGEN SENSORS AND REPLACED THE BRAKE PEDAL SWITCH TWICE, BUT OVERALL WITH RELIABILITY I HAVE NOT HAD ANY PROBLEMS. IT IS A GREAT CAR. AT AROUND 100,000 MILES, RUST STARTED SHOWING UP BY THE WHEELS. IT IS AWD, SO IT DOES WASTE MORE GAS. I AM GETTING ABOUT 14 CITY AND 19-20 HWY. IT IS A 13 YEAR OLD CAR, SO THINK ABOUT THAT. IT IS GREAT IN THE SNOW, NEVER GOT STUCK ANYWHERE. GREAT PERFORMANCE FOR A 3.2 LITER. TREAT THE CAR WITH FULLY SYNTHETIC OIL AND PREMIUM GAS, WHICH I ALWAYS HAVE. AND THIS CAR WILL LAST YOU A LONG TIME. I HAVE TO CHANGE SOME TIE ROD ENDS RIGHT NOW, BUT I MEAN THE CAR HAS 130,000 MILES AND THEY ARE ORIGINAL."
"My Ml is a tank. I love it.
Burns more gas than I like but well built and reliable.
I just had an accident where I ran over a large cement block that had fallen from a truck at 45MPH
The ML rolled over it, causing damage to the underside of the floor and door. Nothing wrong with the frame or driveline.
Another car would have been road-kill.
If you can find one for under $10K with less than 100K miles - BUY IT!"
"I HAVE AN ML 320 WHICH HAS BEEN A HEADACHE. THERE HAVE BEEN MAJOR REPAIRS AND I AM CONTINUALLY AT THE DEALERSHIP. I WOULD NEVER RECOMMEND THAT ANYONE BUY A MERCEDES. THIS IS MY 2ND ONE AND MY LAST. THE REPAIRS ARE ASTRONOMICAL. THERE ARE A FEW GOOD FEATURES - IT HANDLES WONDERFULLY IN THE SNOW AND IS A COMFORTABLE RIDE. BUT UNFORTUNATELY THOSE DO NOT MAKE UP FOR ALL THE MECHANICAL ISSUES."
