Famous quotes containing the word car:
“Fifty years from now, it will not matter what kind of car you drove, what kind of house you lived in, how much you had in your bank account, or what your clothes looked like, But the world may be a little better because you were important in the life of a child.”
—Anonymous. Quoted in The Winning Family, by Louise Hart, ch. 1 (1987)
“The reason American cars dont sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. Thats why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
