I bought this with 95k miles for about $14k. Now it has 135k. It has been the best car I have ever owned. Fast, safe (a deer hit me and almost no damage), quiet and comfortable. I love it. From what I have read that other Benz' are not as good. One thing to beware of. This is a benz and they are not cheap to maintain.
Speed at 70 mph. You step on the gas and you get to high speed in seconds. You really gotta watch.
Make the rest of the benz line as good as this one. I have been toying with getting an ML but have not read much good about them.
