This is the first MB I've ever owned and its the best car I've owned. I have had several luxury vehicles and am a chauffeur by trade. I have over 250000 miles on it and you would never be able to tell it. Im going to try to get at least 400000 miles same engine/trans.
I have major suspension problems and the trunk looks open all the time.I have had to repair the suspention/ air shocks 3 times at $4,500 a whoop! There should have been a recall on the suspension system it is dangerous and costly. I have broken down 3 times with my car sitting on the street like a lower rider, SHAME ON MERCEDES BENZ
