 The result was the successful Ford Model A, introduced in December 1927 and produced through 1931, with a total output of more than 4 million.Subsequently, the Ford company adopted an annual model change system similar to that recently pioneered by its competitor General Motors (and still in use by automakers today).Not until the 1930s did Ford overcome his objection to finance companies, and the Ford-owned Universal Credit Corporation became a major car-financing operation.
