I drive a car that gets ~38 MPG, it's also heavy... and 30 years old. 
It's also a diesel that was made by GM doing a retrofit of their existing gasoline engine (ie it wasn't actually designed for diesel).
So when the car companies say crap like their small, light cars are good because they get 35 MPG it kinda pisses me off.

Very interesting!! Is that an estimate or actual combined mileage? What is the engine displacement? Is it normally aspirated? To drag that huge hunk of steel around with mileage figures like that, you must drive very, very slow.
My 23 mpg car actually gets 28, if I drive it right. But I paid good money for 306 hp, so I use it—often! :-)
My Toyota gets 43 mpg as long as I drive just under the speed limit. The only problem is that it wasn’t manufactured in America. It was manufactured in the Peoples Republic of California.
