Two Porsche 911 S/Ts, one limited-edition number

To celebrate the 60th anniversary of its iconic sports car, the 911, Porsche produced the 911 S/T. The special edition was limited to just 1,963 units, with the 911 badge on the passenger side of each car's dashboard bearing the personal limited-edition number of the special model.

But it turns out that the number 1724 accidentally appeared twice and was already delivered to two of the marque’s customers. The faux pas came about during the manual ordering process of the additional customised badge for the customers' cars.

To commemorate the double rarity of their 911 S/T, both received a picture of the two cars, with their correct limited-edition numbers, as well as an elegant box with samples of the respective interior and exterior colours

Deciding to right its wrong and to commemorate the double rarity, Porsche invited both customers together for a special day in Zuffenhausen. Both customers received a picture of the two cars, with their correct limited-edition numbers, as well as an elegant box with samples of the respective interior and exterior colours.

In order to officially document the error as part of the company's history, the incorrectly installed plaque was handed over to Frank Jung, head of the company archive, and catalogued and stored while the customers looked on.
