CarMax Car Buying App
The CarMax app for iPhone and Android delivers a great way to look at used cars and to see the pricing without dealing with a dealer when you start the process.
CarMax offers a used car dealership that can take some of the stress out of buying a used car. The company lists a price for the car that cuts out a lot of the negotiating.
It's kind of like the TrueCar app for used cars, but it only searches the CarMax locations. There are many of these, but you may have to travel farther than to your local dealer, so keep that in mind as you do your research.
