GM was initially created by combining independent manufacturers who were competing with the Ford Motor Company and vehicles offered before the October 1, 1908 introduction of the Model T. Once the Model T began to dominate the market, independent companies began to combine their resources as corporations and decided to offer what the Model T didn't. The Model T was offered in black because it dried the fastest as it rolled of the assembly line, so GM offered their products in various color combinations; the Model T came with one four-cylinder engine, so GM offered their vehicles with different wheelbases and engine displacements on a gradual scale based on price.
