Famous quotes containing the word car:
“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)
“It all began so beautifully. After a drizzle in the morning, the sun came out bright and clear. We were driving into Dallas. In the lead car were President and Mrs. Kennedy.”
—Lady Bird Johnson (b. 1912)
