2001 Mercedes-Benz M-Class ML320 AWD 4dr SUV (3.2L 6cyl 5A)
Bought it with 35,000 miles and I have just put 37,500 more miles in 4 years. It had brand-new tires and brake-pads when bought and it is just about time to replace them. I have spent about $500 a couple of time extra for repairs (not regular maintenance) and my only complaint would be that I have to keep an eye on the engine oil level. If I drive over 70 miles per hour on a hot day, it will surely burn oil. Other than that I am pleased with this SUV.
It is a tank in the highway, I feel safe and enjoy the drive. Although you may feel it is underpowered, it has always responded very well when needed. Brakes have saved me from 2 car accidents, so it is a reliable SUV!
It feels kind of slow when you start accelerating, but the reality is that it is a heavy SUV, what could I expect for a 3,200cc engine.
