Pierre Richard
This car also appears in many films with Pierre Richard.

Louis de Funes
Also the car appears in many films with Louis de Fines. Unfortunately in the following scene it gets destroyed.

Le Fabuleux destin d'Amélie Poulain
In the famous Film The Fabulous Destiny of Amelie Poulain (Le Fabuleux destin d'Amélie Poulain) the 404 has a short appearance at the beginning.

Beatles
The car that was shown here was a BMC Farina. It looks very similar to the 404 and so I use this correction for announcing that there soon will be a new Similar-Cars-Section on this site!
