Ugh, the voice-overs just kill this. The info and footage is great but whoever decided that the voice-over should sound like it was coming from a transistor radio from the 60s should never get another job in film. This just makes it difficult to watch. There are so many good story lines and just as you are enjoying the story they cut to some footage with a voice-over that is from someone clearly not involved in racing and then they make that worse by the fake radio announcer sound.
