Auto Care Association, MEMA Aftermarket Suppliers Release 2025 Joint E-commerce Trends and Outlook Forecast Report

BETHESDA, M.D. and RESEARCH TRIANGLE PARK, N.C. —  The Auto Care Association and MEMA Aftermarket Suppliers have released the 2025 Joint E-commerce Trends and Outlook Forecast report, providing updated insights into consumer purchase of automotive parts and accessories via the online channel. Released at the 2025 AAPEX tradeshow in Las Vegas, Nev., the report provides in-depth analysis and forecasts to support the industry’s continued adaptation to consumer behavior for research and purchase of automotive parts and accessories. 

Research and analysis for the 2025 Joint E-commerce Trends and Outlook Forecast were led by Jefferies, with a team of leading industry collaborators. 

Consumers have continued to seek lower prices for automotive parts via online retailers as inflation has persisted. When third-party marketplaces are excluded, e-commerce sales are projected to grow 4.6% in 2025 and at a compounded annual growth rate (CAGR) of 5.4% from 2022-2030. When complete sales for Amazon, eBay Motors and Walmart are included, total channel sales are projected to grow at a 6.7% annualized growth between 2020 to 2030. 

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. 

The 2025 Joint E-commerce Trends and Outlook Forecast report provides data and insights for online sales of selected parts categories.  While some product lines experience seasonal trends for online purchases (e.g., HVAC), many do not (e.g., brakes, steering and suspension). Ticket amounts for parts categories have grown at up to 6% year-over-year from 2021-2025, albeit mostly attributable to inflation. 

“Readers will learn whether DIYers are more likely to order online from exclusively online providers like Amazon or Rock Auto vs. brick-and-mortar stores, as well as compare product category performance in the e-commerce channel,” said Michael Chung, senior director, market intelligence, Auto Care Association. 

“The percentage of consumers starting their in-store purchasing journey online has grown steadily since 2018, emphasizing the importance of an online presence and an e-commerce strategy. Our partnership with the Auto Care Association keeps both Auto Care and MEMA members well-informed to navigate evolving consumer preferences and changing market conditions,” said Philip Atkins, director, strategic research and planning, MEMA, The Vehicle Suppliers Association.
