Internally known as the type 930, the Porsche 911 Turbo arrived in 1975 as something altogether new and, in many ways, it still feels that way today. As the very first year of production, examples such as the one on offer showcase a particularly unique place in the models history, capturing the 911 Turbo before refinement softened its edges, when it was still a direct translation of Porsches turbocharged racing ambitions into roadgoing form. For many, that rawness is exactly the point.

According to its accompanying Porsche Certificate of Authenticity, this example was delivered new to the German market finished as it is today in Grand Prix White over black leatherette with black corduroy seat inserts. Its specification is notably purposeful: It was ordered as a radio-delete, though fitted with a manual antenna, and equipped with an electric sliding sunroof, sport seats, an uprated 88-amp battery, and Pirelli tires. Completed in June 1975, it was sold through Gl ckler in Frankfurt to its first owner, reportedly a journalist with Die Zeit, a German paper-of-record. The car is believed to have remained with its first owner until around 1979, when it was sold and exported to Japan. There, it was acquired by an enthusiast in Gifu Prefecture, who used it sparingly before placing it into storage in the 1980s, where it would remain for decades.

Rediscovered by a Canadian enthusiast, the car was exported to Toronto for a thorough mechanical and cosmetic recommissioning beginning in 2017 by SEM Motorsports. The work was comprehensive, including a full engine rebuild with new head studs, seals, bearings, and tensioners, along with attention to the brakes, fuel system, suspension, electronics, and clutch. Most recently, in July 2026, the Porsche was entrusted to the experts at European Collectibles in Costa Mesa, California, for a fresh servicing and fluid change.

Rarely does such an early, thoughtfully specified, and wonderfully preserved 930 Turbo become available, offering an exceptional opportunity for the collector seeking a landmark Porsche equally suited to presentation or spirited driving.
