This is the greatest film made with a car in it. period. Watch it and get blown away. Claude Lelouche you are a god.
The film was spontaneously shot in the early morning hours of a sleepy paris in 1976 after Director Claude Lelouche and some friends decided to strap a camera to the front of his Mercedes 450SEL and floor it. There was no other preperation involved and the film was shot in one go. Later Lelouche re-did the exact same route with a Ferrari 245 in order to dub a better engine sound over that of the Mercedes.
