When it comes to buying and selling cars, Auto Trader is one of the most well known names in the business and the company's iPhone app makes it easy to search for the car of your dreams. All you need to do is input your vehicular preferences, specify how far you're willing to travel and the app will return a series of matching results.
You can then view the online advertisement for individual cars which include photographs and contact details for the seller. Reviews are also available so you can check what the experts think of any purchases you are thinking of making.
As you're browsing through a number of cars you can opt to save them to your 'garage' so they can be easily referred back to later. This is useful if you want to compare a number of cars and is a great alternative to pen and paper.
If you're out and about and spot a car you like the look of, you can use your iPhone's camera to take a photograph of the number plate. The app will then track down reviews and technical information so you can search for similar cars that may be for sale.
