car companies ready to take care of
the demands OF both owners and
dealers for high-grade. dependable
automobiles in quantities.
THE predominating characteristic
Of Buick cars, and the one that more
than all others has given the name
Buick its prestige in motoring circles
is the valve-in-head motor" says
Frank D. Garinger Of the Springfield
Buick Company.
THE interest Of the motorist logi-
cally centers about the motor in his
car, because the motor is the source
of power and locomotion, and its
gasolene consumption is a fixed item
Of expense.
Therefore. the principle Of motor
design thai combines the greatest
power with the lowest consumption
Of gasolene is the most satisfactory
from the standpoint Of the owner.
II means motoring efficiency in its
truest sense. And the type Of motor
which gives this efficiency is the
valre-in-head type.
For nearly 70 years the Buick
Motor COMPANY has cor cenr:ated OF
the development Of the valre-!n -head
motor. and as n result the Buck
motor combines all the possibilities Of
this type in a remarkable manner
There are definite scientific rea :
sons why the valve -in-head meter
possesses marked advantages Owe
other types Of design.
