2006 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)
The only problem I have had is one of the chrome wheels had a crack in it. It was replaced with no problems, except that it took 2 days to get a replacement. But the dealer gave me a replacement vehicle so there was really no problem. Another problem (but not with the car) is it is very easy to go very fast in this car and not feel like you are even moving, its so smooth for an SUV.
Ease of driving and believe it or not I love the steering column mounted shift lever and the steering wheel shifters. It becomes second nature in no time at all.
The price could be lower, but then I guess it wouldn't be a Mercedes
