By 1909 the vogue of Stock-Chassis racing had become widespread; the direct result of the practical demands engendered by the fast-growing acceptance of the automobile. The car, no longer a mere sensational symbol of speed, was becoming a utility. Indeed, Ford's "Universal Car", the model T, was not far distant. Motoring, in the restricted fashionable sense, was past, and automobiling for pleasure and for business loomed promisingly for the great general public. Thus the cars being designed for this huge potential market came to replace the specialized racing creation, and Stock-Car racing, on road and track, reflected the social trends as well as the business acumen of our way of life. The Vanderbilts of 1909 and 1910 were Stock-Car contests and the last of the great Cup Series on Long Island. The classic-phase passed from the Nassau County roads to Savannah where the lingering "old-school exponents" race the pure thorobreds for America's Grand Prize. Furthermore, to insure opportunity for all, these last Cup Races were supplemented with minor contests for the smaller machines and in all classifications there were strict limitations of engine size. It is doubful if Mr. Vanderbilt anticipated this turn of affairs when deeding the Cup five short years before.
