Yesterday, released a rental car reservation app for the iPhone, allowing you to reserve a car from any Avis rental location with an easy tap-and-type interface that's easier than using a web browser.

Although we think maybe they need to have someone take a quick run-through of the pictures they're using for each vehicle. Somehow we don't think the Ford Fusion's a GM product (check the gallery for further proof) or that there's any Avis location that'll rent you a Pontiac G8 GXP.

Also, for some reason, it shows that Detroit Metro airport has no cars to rent. Ever. Somehow we don't think Detroit's such a tourist and business attraction that they've completely sold out. But otherwise, the app seems fairly robust. Check it out in the gallery below, or download it . Don't worry, it's free. Unlike the "GPS upgrade" on your rental.
