For the sixth consecutive year Buick has been assigned first place at the National Automobile Shows which will be held in the United States during January 1924.

As has been the case in previous years, the choice of positions was made on the basis of the greatest dollar volume of business done by manufacturers during the year at hand. The fact that Buick has been given first place six times in succession is convincing evidence of Buick's leadership, and the leadership of General Motors, in the automotive world.

Buick is now producing over FOOD cars a day-the greatest production in its history.
