Smartphones are dangerous when you're at the wheel, but they can come in handy if you're taking your car in for repairs, shopping for new wheels, or even if you're locked out.

Increasingly, auto shoppers want to research cars during the week on their home or work computers and then access that information on their smart phones in the showroom on the weekend. A spike in traffic from mobile devices on weekends confirms this pattern, says CEO Chip Perry of, the largest online site for car ads. In response, AutoTrader set up a special site to handle mobile apps for iPhones, Android-based devices, and other smartphones.

OnStar ($199 a year) is principally a safety and security service with live operators who call 911 if they detect your car has crashed.

On AutoTrader's streamlined mobile site, you can comparison shop: While kicking the tires in one showroom, why not check to see if the same car is advertised at a lower price in another nearby dealership.

Find Dealers If an AutoTrader ad or the Edmunds inventory function shows a similar car nearby, you can get a map to get to that dealership. They also will show you dealership phone and e-mail contact information. Hey, why not put your salesman on the phone with his counterpart at the other dealership. Let 'em bid for your business.

"People now are used to shopping on the Internet and just clicking to buy. Shopping for cars can seem like being on another planet," says Edmunds CEO Jeremy Anwyl. "Having access to the information they need on their smart phones will make a lot of shoppers feel more at home."
