(These are all high rez, and so if you click on them you should be able to read even the small type.) From 1908 to 1927 Henry Ford produced the Model T with only modest changes, which was very successful for 15 years or so, but then almost brought Ford Motor Company to disaster. By the mid 1920s for just a little more than a Model T you could get a Chevrolet that was more powerful, more comfortable, and more stylish. And for just a little more than that a Pontiac that was even nicer, or for a bit more an Oldsmobile that was an excellent car for the time, and then for just a little more than that a Buick that was almost as good as a Cadillac. GM with its modern management under Alfred Sloan, armies of engineers, and a commitment to continual technological improvements and styling changes by 1927 was quickly surpassing Ford and its backward Model T kept frozen by Henry Ford's closed mind. GM's advertising was also more plentiful and often better than Ford's. GM even ran a series of more than a dozen ads about how they had an "Open Mind" compared with Henry Ford's closed mind. When Ford ended production of the Model T in late 1927 they didn't even have a new model to sell, and so Ford dealers had to keep themselves afloat with used cars for almost a year. But finally in 1928 Ford introduced the Model A that was a big leap forward—and which was suddenly as good in most ways as a Chevy, and in some ways better. For more than a year Ford came roaring back with the Model A, although in terms of total sales GM was still ahead.
