Dealers can now post used vehicles on Cars.com with vehicle history reports from Carfax Inc. or Experian Automotive's AutoCheck.
Before the beginning of this year, Carfax was the exclusive provider of the reports on Cars.com.
"It's an effort to give our dealers a few more options, and [more options for] consumers as well," says Tom Muellner, an associate marketing manager at Cars.com.
In cases in which a dealer subscribes to both Carfax and AutoCheck reports, the Carfax report appears with the vehicle listing.
That's because of the longstanding partnership Cars.com has with Carfax, Muellner says.
"They are still the preferred history report vendor for us," he says.
"The majority of dealerships still use Carfax, so between that and the consumer recognition of Carfax as a leading vehicle history report provider, that's why we kept it the way we did."
Carfax had an exclusive deal with AutoTrader.com to provide reports until the renewed partnership agreement between the companies dropped the stipulation as of last Sept. 1.
Since then dealers have had the option of posting used vehicles on AutoTrader.com with vehicle history reports from Carfax or AutoCheck.
Last April, the owners of 120 auto dealerships filed a federal lawsuit against Carfax alleging that the company engages in anticompetitive practices and violates antitrust laws.
It alleges that Carfax mono-polizes the sale of vehicle his- tory reports through exclusive agreements with auto companies and popular classified auto Web sites.
The suit seeks damages of more than $50 million.
The list of plaintiffs had grown to 500 by the first week of January, according to a press release from one of the plaintiffs' law firms, Bellavia Blatt Andron & Crossett of Mineola, N.Y.
