An anniversary model of the Porsche 964 was produced, which stands out from the series models thanks to its particularly extensive and, in some cases, unique equipment. From 1993, a series of the 964 limited to 911 pieces was launched to celebrate the 30th anniversary of the Porsche 911. These vehicles were built in the 1993 "P-Program" and 1994 "R-Program" model years. The special model "30 years 911" was the all-wheel drive "Carrera 4" variant of the 964 with the wide coupé body of the turbo model. However, the voluminous rear spoiler was dropped in favor of a more harmonious and elegant shape. The automatically extendable rear spoiler remained the same as on the standard models. Basically, the model was only available in three paint finishes. Viola Metallic was the exclusive color for the German market. Most special models were executed in this colour. In addition, there were amethyst metallic and polar silver metallic as standard colors. Externally, the special model can be recognized by two plaques on the parcel shelf. One of them bears the engraved limitation number of the respective vehicle and the lettering "911 30 years" is on the engine cover.
