CineFiat made promotional videos for all models and the Fiat 850 was no exception. You can easily find them on Google. Beautiful films were made and yet they never won an Oscar.
As far as I am concerned, this is one of the best. The Fiat 850 was presented in a grand and compelling way: images from the factory, transport and a promotional ride with cheering public along the side. Everyone was happy with the 850.
