According to the video uploader:
Taking part are a whopping 350 cars; counting around 60 Aventadors including the new Aventador Roadsters, a few Murcielago LP670 SVs, LP650 Roadsters, all versions of the Gallardo including the Blancpain and Super Trofeo Stradale, more LP640s, Diablos, Miuras, Countaches, and even some tuned or custom cars from Liberty Walk in Japan and others.
So awesome. I wonder what security is like here. I see a few guards, but not many.
