I'll echo most of the others .... in the short time I've had my '97 E420 I've averaged about 20mpg. It does love the open highway and being able to READILY pass someone at 80+ you can understand that the car really begs to be based out west <VBG>. I drove my Supra cross-country and back this year and really would love to do the same in the Benz.
