Although we bought this car used, it has only been fun to drive for the first 4000 miles, then major things started breaking down in this car. Computer Module at 90k, $1000 repair. Then, cracked radiator at 92k, $900 repair. Then, 110k, tension belt and pulley blow out, $550 repair. Also, these repair are being done by mechanic, which is way less than what the dealer would charge. Normal wear and tear items like tires, brakes,
and oil changes are very costly. It's a nice car, but it is becoming really difficult maintaining this vehicle. Also, the interior trim was made with cheap plastic, and is breaking. We expected better from a Mercedes-Benz product, and will not buy another.
Car is a pleasure to drive. Purchased with 76k. ABS pump, ebay 46.00,mechanic 1000-1400 , ps rack 650.00 mechanic 1500.00, front pads, sunroof issues, catilytic converter broke in two, had it tig welded .overall very happy but I am fairly skilled DIY, don't buy if you are relying on dealer or mechanic to fix your maint. issues .
I have owned this car for 10 years now and i am still trusting it. It had some minor problem but so has every car. The only problem is the interior parts are not very durable. Little things like the door panel, handle, seat panel etc. Otherwise, it is a very reliable car. In fact, it is more reliable than my newer BMW 7 series. I will get another Benz because of the reliable engine and trans and the comfort, not sure if it will be an SUV but might consider the E class. the m class is pretty worth it for the price and re sell is not bad at all.
I've had the car half a year and what I have to say that it's a gas guzzler will never buy another Mercedes again, interior and exterior don't have the greatest design, mostly bought because of the name, but I got tricked on this one.
