I've been seeing this spot on TV for the C230.

The spot is all about gas mileage. They brag about the fact that the car is finely tuned and can get 25MPG on the highway.

I don't get it. Both our 300Es from the early 90's routinely get about 28 MPG on the highway.

Why is MB patting themselves on the back about a C230, a lighter, smaller, newer-technology car than an old 300E, getting 25 MPG?
