Yahoo hopes to broaden its business relationship with Cars.com as it expands its power in vertical-friendly sites.

The elaborated Cars.com liaison would follow Yahoo's newspaper consortium model: each party may sell inventory on another's site. Yahoo calls this the "We sell, you sell" model.

This will broaden the advertising opportunities on Yahoo's recently-launched AMP ad platform. It will also avail Cars.com's local ad dollars to the search firm.

Yahoo currently displays targeted auto listings on Cars.com, based on pages previously viewed by users.
