CarMaxWhile CarMax's app is "limited" to the used car dealers' nationwide inventory, it allows one to search nearby stores and get vehicles transferred to one for a test drive — often for a price. The ability to compare vehicles on the search results screen is convenient if one knows what they're looking for, as the comparison screen lists everything from engine size to the sound system to options like blind-spot monitors and seat heaters. The app also guides users through a series of general questions and options to narrow down the hunt.CarMax's app launches with an optional sign-in, followed by a menu of vehicle categories like gas, electric, convertibles, pickup trucks, and sports cars. The next screen asks users for financing information to help narrow down a budget, and that's followed by a lengthy features list if things like a fold-away middle row of seats or a full roof rack are non-negotiables. That takes users to a fairly barebones results list, with each listing consisting of just a photo, price, mileage, and location. Click through and features, specs, photos, and pricing information (CarMax emphasizes a no-haggle pricing system) are all listed.Some vehicles also have a 360-degree view of the interior. Tabs to reserve the vehicle at a nearby CarMax store for further inspection, to pick up the vehicle for purchase, or to have the vehicle delivered to one's home are also large and right in the middle of the results screen.
