A vintage car is, in the most general sense, an old automobile, and in the narrower senses of car enthusiasts and collectors, it is a car from the period of 1919 to 1930. Such enthusiasts have categorization schemes for ages of cars that enforce distinctions between antique cars, vintage cars, classic cars, and so on. The classification criteria vary, but consensus within any country is often maintained by major car clubs.
The vintage era in the automotive world was a time of transition. The car started off in 1919 as still something of a rarity, and ended up, in 1930, well on the way towards ubiquity. In fact, automobile production at the end of this period was not matched again until the 1950s. In the intervening years, most industrialized countries built nationwide road systems with the result that, towards the end of the period, the ability to negotiate unpaved roads was no longer a prime consideration of automotive design. In today's terms, a vintage car is defined the same as a classic.
Cars became much more practical, convenient and comfortable during this period. Car heating was introduced, as was the in-car radio. Four-wheel braking from a common foot pedal was introduced, as was the use of hydraulically actuated brakes.
Towards the end of the vintage era, the system of octane rating of fuel was introduced, allowing comparison between fuels. In 1923 the gasoline additive Ethyl made its debut at the Indy 500 that resulted in a boost in octane from the 1950s to the 1980s In the United States drive-in restaurants were introduced as well as suburban shopping centers and motels.
Alfred P. Sloan and Harley Earl of General Motors, and Walter P. Chrysler capitalized on advertising the automobile’s role in the life of the consumer for more than just the utilitarian value compared with the horse. The stock market crash of 1929 started the layoff of automotive workers and many new companies went bankrupt but over two million cars were still produced in 1929 and 1930.
