The hot rod is an American invention. The vehicle typically is based on an American built car of almost any vintage, and then modified to improve performance and personalize appearance. Early hot rods were often based on depression era roadsters as these cars were light and cheap during the 1940s and 1950s when building hot rods became popular. In many cases, the modern hot rod builder utilizes a more current vehicle as a base and may have a wider selection of sources for parts.
