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 states 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.
For the average person car collecting is a hobby. A person usually has a fascination with a certain vehicle or a history with one so seeks a certain make or model. Finding an antique car at an affordable price is not hard but can be relatively expensive depending on the condition or the desired end result. The less work required on a vehicle equates to a higher price. The more work required means a cheaper initial cost, but more in the long run, and a person's level of restoration experience plays an important part.
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.
