Famous quotes containing the word car:
“I marched in with the men afoot; a gallant show they made as they marched up High Street to the depot. Lucy and Mother Webb remained several hours until we left. I saw them watching me as I stood on the platform at the rear of the last car as long as they could see me. Their eyes swam. I kept my emotion under control enough not to melt into tears.”
—Rutherford Birchard Hayes (1822–1893)
“The reason American cars don’t 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. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
