Used car prices are available for 1989 model year and newer. Photos of new and used cars are also featured on the iPhone site. By touching the NADA icon, Apple iPhone and iPod touch users can also access the main site, http://www.NADAguides.com, for additional information, such as car specs, video car reviews and pricing information for other types of vehicles, such as classic cars, boats and ATVs.

"This is a terrific tool for shoppers who need information at their fingertips, while they are out  shopping on a weekend," says Tara Baukus Mello, senior writer and lead market analyst at NADAguides.com. With a few simple clicks, a  shopper can know in an instant whether he is getting a good deal on the car or ATV he's considering buying, as well as on his trade-in.

"NADAguides.com knows how important it is for car and ATV shoppers to be able to access new and used car prices conveniently and easily and we are pleased to be able to provide technology to support the new iPhone 3G," says Don Christy, Jr., President and CEO of NADAguides.com.

The NADAguides.com iPhone site was designed for Apple's iPhone 3G, which went on sale last week, but can also be viewed on the first generation iPhone and iPod touch devices. Access it at iphone.nadaguides.com.
