 This Mercedes was good in its day but has been far exceeded by the likes of Lexus, and BMW. Gas mileage is horrible. You can expect 17-18 at best on long trips, 11 to 12 around town. For the same price you are better off with the E-350 4 matic which will deliver 24-25 mpg. The navigation although accurate is ancient (look at the Lexus) You'll think your comparing a video game from 1995 to 2005. Unfortunately the new Mercedes ML is not much better.You'll also find operating the navigation consists of moving a joy stick. Unfortunately this has also carried over to the new ML. Pretty stupid! Electronics and comfort features are deffinately not Mercedes strengths. Also braking is heavy.
