We got the E280 for one year in the U.S. - 1993. I have one - a sedan -which my wife drives and likes very much. The EPA numbers for the car are quite a bit lower than Dean quotes - 19/25, actually. These are pretty much spot on my experience. I think the 3.2 liter was 18/24; haven't looked lately.

A wagon uses more fuel than a sedan - it's heavier and has poorer aerodynamics. The first hurts city fuel economy, the second highway.

A Euro car may have a standard transmission and higher compression engine - both should help fuel economy somewhat.
