A vintage car is commonly defined as a car built between the start of 1919 and the end of 1930 known as the "Vintage era". There is little debate about the start date of the vintage period—the end of World War I is a nicely defined marker there—but the end date is a matter of a little more debate. The British definition is strict about 1930 being the cut-off, and is widely accepted while some American sources prefer 1925 since it is the pre-classic car period as defined by the Classic Car Club of America. Others see the classic period as overlapping the vintage period, especially since the vintage designation covers all vehicles produced in the period while the official classic definition does not, only including high-end vehicles of the period. Some consider the start of World War II to be the end date of the vintage period.
