How Porsche Addressed a Duplicate Limited Number on the 911 S/T

Porsche reports how a manual ordering error led to two 911 S/T cars sharing one limited number and how the issue was formally resolved at the factory.

Sometimes the most revealing stories about a brand emerge not from major launches, but from human imperfection. With the Porsche 911 S/T, a small mistake during the individualisation process turned into a moment that now forms part of the company’s documented history.

The anniversary 911 S/T was created to mark 60 years of the 911 and limited to 1,963 units. Each car carries a personal limited-edition number on a badge mounted on the passenger side of the dashboard. During the manual ordering process for this bespoke element, the number 1724 was assigned twice.

One of the cars was delivered to Pedro Solís Klussmann in Guatemala, for whom the number carried deep personal meaning, referencing several family birthdays. The other went to Suzan Taher, whose car was originally intended to bear a different number. When Porsche discovered the duplication, the company chose a transparent and unusual response.

Both owners were invited to Zuffenhausen for a special occasion. Porsche formally apologised, corrected the mistake and preserved the incorrectly installed plaque in the company archive, officially cataloguing it as part of its history. The gesture reflected the philosophy behind Sonderwunsch, Porsche’s special request programme rooted in craftsmanship and hands-on processes.

Apart from briefly sharing a number, the two cars are entirely different expressions of individualisation. Klussmann’s 911 S/T features the Heritage Design package with Shore Blue Metallic paint and historically inspired interior materials. Taher’s car stands out in Paint to Sample Plus Rose Red, a colour known in the 1970s as “Fraise” and associated with iconic racing-era Porsches. Following this commission, the shade was approved for inclusion in Porsche’s regular Paint to Sample programme from the 2026 model year.

At its core, the 911 S/T remains a purist driver’s car, powered by a naturally aspirated 4.0-litre flat-six engine producing 525 PS, paired with a manual gearbox and a consistently lightweight construction. The model’s name references the original 911 ST competition cars of the late 1960s, and this unexpected numbering episode adds another human chapter to that lineage.
