Edmunds.com, Inc. is an American online resource for automotive information. The company is headquartered in Santa Monica, California and maintains an office outside of Detroit, Michigan. Edmunds.com is privately held, with the Steinlauf family holding a majority stake.

The Edmunds.com Web site includes prices for new and used vehicles, a database of national and regional incentives and rebates, dealer and inventory listings, vehicle test drive reviews, and tips and advice on all aspects of car purchases and ownership. In addition, the company circulates free e-mail newsletters to voluntary subscribers.

Edmunds.com provides data through its "True Market Value" pricing tools, which launched in 2000. The Edmunds.com True Market Value New Vehicle Calculator provides the estimated average price consumers are currently paying when buying new vehicles. The Edmunds.com True Market Value Used Vehicle Appraiser estimates the actual transaction prices for used vehicles bought and sold by dealers and private parties.

In 2005, Edmunds.com launched Inside Line, a free online magazine for automotive enthusiasts. Inside Line delivered automotive content in the form of videos, photos, blogs, news articles, discussion boards and road tests. In 2013, Edmunds.com shut down the popular site despite complaints from loyal visitors.
