Fiat really made sure to make its "nuova 500" a work of art. There are plenty of details like this all around. The headlights, by the way, much like the brakes, suspension, tanks, etc. etc., were reworked to please the American market (and adhere to local vehicle safety codes). Much to my delight, as the changes seem to have overall resulted in a much better version of the car (with the exception of the taillight design, perhaps).
