YouTuber 356Daly recently spotted a test mule driving around Maranello and he seems to think that it's actually a new F12 model. In the video's description, he also notes that the car is rumored to come with the name "F12 M," and that it will be released into the wild in early 2017. After watching the video, it's very possibly that the car in the video may be a F12 successor due to the Grand Tourer layout. But, time will only tell.
