To answer your question (though late), I've heard there will be some soon. A modified version of Nissan's Cube is supposedly coming, as is a little 3-cylinder Dodge sports car called the "Slingshot." But I doubt they'll really be available in numbers until people wise up and ditch those SUVs. Few really need them.
