General Motors announced today that its catalog of 45,000 repair and maintenance parts will be available on an online storefront through Chevrolet, GMC, Buick, and Cadillac’s websites.

The new digital marketplace will include ACDelco parts such as oil filters, batteries, brake pads, and more. The automaker also plans to eventually offer digital products through the same storefront. This means you’ll be able to buy a Super Cruise subscription or personalization themes for in-vehicle screens through the same site that you buy windshield wipers.

“We are placing software and digital services at the center of every part of our business,” said GM Chief Digital Officer Edward Kummer. “The future of GM retail lies at the intersection of digital and physical e-commerce. Whether it’s selling parts or vehicles, GM will meet our customers where it’s most convenient for them.”

For physical parts, customers will be able to choose between delivery or pickup at one of GM’s more than 800 participating dealers. Items purchased through the site are also eligible for Chevrolet, GMC, Buick, and Cadillac rewards programs.

“Making our parts available online marks another step in transforming the ACDelco and GM Genuine Parts brands,” said John Roth, GM’s customer care and aftersales global VP. “Our premium parts are engineered with exceptional quality to provide assurance to our customers. The launch of this trusted online sales channel extends that peace of mind to the parts-buying experience.”

GM estimates that the online sale of parts and accessories will make up a $40 billion total addressable market by 2030.

Ultimately, GM hopes to expand its digital storefront in the future to allow customers to even shop for, buy, and finance electric vehicles entirely online. Together with its upcoming subscription services, digital services will potentially amount to $20-25 billion in annual revenue that it expects to tap into.
