The Edmunds research function allows you to dial any make, model, and year to view a vehicle's features and specifications, safety ratings, driver reviews, and local pricing for new or used vehicles.
For used cars, Edmunds delivers a handy chart showing what the car is likely to be worth as a trade-in, private sale, or dealer retail.
However, while hunting for specific makes and models of used cars, results behind an "inventory" button on the Edmunds screen were missing. Instead, a note said: "Used cars coming soon! Currently, we are working to fill-up our virtual lot with cars in your area."
AAA Auto Buying Tools is a new-car-shopping app for iPhone that's free from the national auto club. It begins by asking for your zip code.
Then you can "build a new car," or, if you happen to be wandering the local car lot, enter a specific car's vehicle identification number, or VIN. You find the VIN for a new car on its window sticker. The app retrieves the factory specs for that car.
You can enter a used car's VIN, too, and view its safety ratings and other details, but the results will include the old car's price when it was brand-new.
Information on cars includes estimated dealer costs, options, and safety ratings. The app also includes a "AAA Member Price" for vehicles, representing a discount that some dealers will honor for auto-club members.
NADA Pricing is the free, advertising-supported iPhone application from the National Auto Dealers Association, publisher of the traditional yellow and blue car-price books. It identifies nearby dealers for whatever make you like, and Google Maps their locations.
On pricing for used cars, it delivers a quick guide based on make, model, year, options, and mileage. Some user reviews of the app complain that currently it only goes back to the 1998 model year.
