1966 Ford Motor Company Quality Car Care advertisement
“Certain parts of Ford Motor Company cars are engineered to tolerances 100 times thinner than this page. So fine a piece of machinery can be for best by the specialists – your Ford or Lincoln-Mercury dealer. See him and be sure.”
“Your dealer has special equipment, such as this “Rotunda” oscilloscope engine analyzer, for the care of Ford-built cars.”
