A bunch of cool Ferrari owners backed by the factory decided to turn up at the Mille Miglia stage in Rome and liven things up a bit, paying homage to the legendary race. The lineup includes different modern and classic Ferraris, plus no less than 17 Ferrari 599 GTOs. This must be the largest GTO gathering yet. They also rev the engines and make some fabulous noise. Thanks to the skillful cameraman, you even get to see how the butterfly valve in the GTO’s exhaust flick open to make that V12 bellow. Awesome video, awesome scenery, awesome cars.
