Car shoppers can now get a good buy with a little help from their friends and Cars.com. The automotive shopping site today announced a new share tool that allows shoppers to share vehicles they’re considering via Facebook and Twitter. Sellers can also share vehicle listings from Cars.com with their networks.

“Before making a purchase, car buyers often turn to the people they trust most to help them with this important decision. We wanted to make it easy for shoppers to share cars of interest with their friends and family,” said Bill Swislow, Cars.com senior vice president of product. “With feedback from their networks, shoppers can feel even more confident the vehicle they found on Cars.com is the right match.”

As social media becomes more popular with consumers, Swislow described the integration of Cars.com with Facebook and Twitter as a natural next step in online marketing. In fact, a fall 2009 study by Ad-ology Research found that 42 percent of recent vehicle purchasers said social networks influenced their decision-making process. They particularly wanted to learn what other car buyers had to say, both positive and negative.

“Shoppers on our site are making greater use of the sharing tools we offer, either to get a second opinion or to help friends and family with their purchase,” Swislow said. “At the end of February, for example, we saw a 25 percent year-over-year increase in email usage and the number of listings sent to a mobile phone.”
