The Fiat 500 F, or Berlina, was produced at the same time when the D and L models were in production, and therefore, it was the most misidentified of all 500 models. From 1965 to 1969, it had the same badging as the 500 D, but it featured front-hinged doors instead of suicide doors. From 1969 to 1972, the 500 F was offered as a more affordable base model alternative to the 500 L, or Lusso. Both cars were very similar mechanically, but they had different bumpers and interiors. The 500 L provided greater comfort and style with its modernized interior, which included a new dashboard.

The final incarnation of the 500 came in the form of the 500 R, or Rinnovata. Produced from 1972 to 1975, this model was powered by an Abarth-designed 594 cc engine that was rated at 23 hp, and it had a full synchromesh gearbox. It was more simply equipped and trimmed than previous 500 models. When the Fiat 126 was released in 1972, sales of the 500 R began to drop dramatically. Production of the old 500 came to an end in 1975.

In the year 2007, which was the 50th anniversary of the launch of the 500, Fiat released the new Fiat 500. This car was styled after the old 500, but it was considerably larger and heavier. It also featured front-wheel drive and a front-mounted engine.
