Greenacres2,
I am so glad you mentioned about the best mileage at about 85 mph. I got into a discussion on this board once about "sweet spots" in engines. These cars are more efficent at higher speeds then most any other car. Most will argue that anything over 60 mph just cuts the mpg. In my 500SEL, I got the best mileage on a trip from NC to FLA. Almost 22 mpg for 1 tank of fuel. I was running with a pack of big rigs at 90 to 100 most of that tank. (Yes, trucks do go that fast and faster). If I run the speed limit of 65 it drops to 19 mpg. Think about something. In Germany, these cars are run at 150mph on the autobauns (sp). If higher speed kills mileage as many say, these cars would have to buy fuel about every 100 miles. That is not the case. I talked to a German who owned a 500SEL and he would only say that the mileage droped very little at high speed. Air drag is a lot more complicated than most people think. It can change at different speeds, sometimes going down at higher speed.
Sorry for the rant, but people need to know.

Paul
