"I have owned this vechicle for 18 months. Seems like every time I drive it there is something not working properly. After a couple of days at the dealer things are better for a while. Then its time for service. Expect $400-$500 for regular service(oil change).Mercedes says to just expect the brake noise there is nothing they can do about it. High price does not equal high quality."
"Has had a lot of little things go wrong. Dealership near us was very good about picking car up, giving us a loaner, and fixing things quickly. It is an expensive car, but it is solid and has a lot of good features."
"I have owned this car for a year now. The first 1500 miles the vehicle had been into the dealership twice. I've had an axle replaced, all brake pads and rotors, and an air bag sensor replaced. Each trip to the dealer is 300 miles one way and I have to have a loaner car each time for at least two weeks. My brakes still make a horrendous noise, very embarrassing. The front end makes a lot of racket when stopping slowly and slowly going over small bumps. I've like my loaner vehicles better than this one and I can hardly wait until I can get rid of it. What a dissappointment!
On the plus side, it has a very smooth ride and is comfortable on long road trips. It also has a lot of power. But the negative aspects, in my opinion, outweigh the pluses."
