With a 2.6% average annual growth rate through 2030, the global automotive aftermarket parts market is still expanding even as supply chain delays sit at the top for 21% of manufacturers. At the same time, U.S. shoppers are moving from browsing to buying, with 19.6% of adults purchasing car parts or accessories online in 2023, while prices rose just 1.6% inflation adjusted from 2022 to 2023. Those two pressures, availability stress and pricing restraint, are a big reason replacement parts keep dominating global sales at 48%.
