• U.S. e-commerce sales of automotive aftermarket parts are forecast to reach ~$23 billion (excluding third-party marketplaces), and $44.6 billion total (including marketplaces) in 2025.
• Steady growth from 2020-2030 is expected (total market CAGR exceeding 5%) as consumers seeking lower costs via online channels amidst persistent inflation.
• Retailers' implementation of technological advancements (e.g., logistics improvements; real-time inventory management; part compatibility for vehicle year, make, model and trim) has enhanced the consumers' online shopping experience.
• Ticket amounts for parts categories have grown at CAGR up to 6% (engine parts) from 2021-2025, albeit mostly attributable to inflation.
• While some product lines experience seasonal trends for online purchases (e.g., HVAC), many do not (e.g., brakes, steering and suspension).
• DIYers are more inclined to purchase from online only sources (e.g., Amazon, eBay, RockAuto) than from brick-and-mortar stores.
