Porsche has confirmed a rare production mishap involving one of its most exclusive modern models, the 911 S/T, after two units were discovered bearing the same limited-edition serial number plaque: “1,724 of 1,963.”
The issue, first uncovered by enthusiasts online, has raised eyebrows within the collector community, where exclusivity and authenticity are paramount. One of the affected vehicles was spotted in Guatemala, finished in Shore Blue—a launch color for the model—while the second, a bespoke Sonderwunsch commission in Rose Red, was recently listed at a Porsche dealership in Germany.
Each 911 S/T was meant to be a uniquely numbered piece of Porsche’s 60th anniversary celebration of the 911, with production capped at 1,963 units to reflect the model’s debut year. The cars, priced from $290,000, blend the high-revving 911 GT3 RS engine with a six-speed manual gearbox and lightweight construction. Their appeal lies not only in performance but also in rarity and the individualized number plaques affixed to the dashboard.
In a statement to CarBuzz, a Porsche spokesperson acknowledged the duplication and described it as an accidental oversight. The company confirmed that it is now in contact with at least one of the affected customers and is working on resolving the issue. Porsche has not disclosed which car carries the incorrect plaque or how the mix-up occurred.
Despite the error, the automaker emphasized that the serial badge is purely cosmetic and does not affect the car’s legal identification. Each vehicle maintains a distinct Vehicle Identification Number (VIN), which serves as its true identifier under automotive law.
While it appears to be a one-off incident, the production gaffe is a surprising blemish on what is otherwise one of Porsche’s most precise and carefully curated limited runs in recent memory.
