The movie although 3 hours long is one of those that movies that does not feel like a dragged out long winded tiring story. It is humerous and factual with some interesting information about building cars. I am a fast car fan with fairly good mechanical knowledge. It's not over done or over the top in mechanical information so that those who no nothing about cars don't understand. I loved the movie and would go see it again. I was shocked to see only a couple of ppl attend the movie theater to watch it. That was disappointing.
