Superiority
A kind and degree of performance so new-so indescribably superior-induced more than twice as many people to purchase. Buicks during the past year as any other automobile listing above $1200. Here is ample reason for discarding old buying habits. Take a Buick. Drive it in traffic. Try it on the hills and on the straightaway. Test it in your own way and at your own pace. Measure carefully every element of performance.
Get behind the wheel and get the facts... then you'll get a Buick! Buick Motor Company, Flint, Michigan, Division of General Motors Corporation
