(4) Absolute reliability—because of the varied uses to which the cars would be put and the variety of roads over which they would travel.
(5) Lightness. With the Ford there are only 7.95 pounds to be carried by each cubic inch of piston displacement. This is one of the reasons why Ford cars are "always going," wherever and whenever you see them—through sand and mud, through slush, snow, and water, up hills, across fields and roadless plains.
