The global automotive parts wholesale market is driven by a fleet of over 1.4 billion vehicles worldwide generating constant demand for replacement parts, and a vehicle manufacturing industry that relies on complex international supply chains. Top wholesale automotive parts manufacturers are concentrated in China, Germany, Japan, South Korea, Taiwan, India, and the United States.
