How many cars in the united states?
In 2009 there were about 246 million cars!
From 1908-1927 Ford Motor Company sold over 15 million Model T Fords. The vast majority of these were sold within the United States. By 1929 Ford had sold an additional thousands of Model A Fords. At the same time Chevrolet, Oldsmobile, Buick, Cadillac, and many other manufacturers were selling cars. So is easy to estimate that there were millions of cars in the United States by 1929.
