PointAbout created the Cars.com app, which was launched on Sunday by Cars.com with a Super Bowl ad.  MobileMarketer reports that the ad generated 6,500 downloads immediately after the ad aired.

MobileMarketer goes on to state, “Cars.com tapped PointAbout to create the application for the iPhone and iPod touch as a complement to its mobile Web site, which was created by Crisp Wireless. General Motors, Toyota, Mercedes-Benz and Ford have all bought display advertising on the mobile site for 2010.”

MobileMarketer continues, “We wanted to be available to all consumers, so we have to be device- and carrier-agnostic, so that if you have a mobile device, you can access all of the tools and the 2 million-plus listings on Cars.com using your handset,” said Sharon Knitter, senior director of consumer products at Cars.com, Chicago.

“About 30 percent of our mobile content is coming from the iPhone, and we have folks that have an iPhone that look at our mobile site, but we wanted to also give them the opportunity to download an app,” she said. “We decided to start with a mobile Web site and add on device-specific apps as the market warrants—Android and BlackBerrry are on our radar.

“Mobile will continue to evolve, and we’ll continue to assess the layout of the marketplace, watch market share and adapt accordingly.”

Here is the SuperBowl Cars.com ad, which includes the app (although the ad used a generic phone for licensing purposes):
