For Sale at Auction: 1990 Porsche 911 in Carmel, California

Chassis No. WP0ZZZ96ZLS404372

Few companies have so thoroughly reshaped the modern collector car landscape as Singer Vehicle Design. Since its founding in 2009, the California firm has built its reputation around an unwavering premise: begin each of its restorations with an air-cooled 964-generation Porsche 911 and, through collaboration with each owner, create an individualized build informed by modern engineering, advanced materials, and extraordinary craftsmanship. Over time, Singer's portfolio expanded beyond its original Classic services-now long sold out-to include all-wheel-drive restorations, Targas, and the groundbreaking DLS services, each exploring a different interpretation of the air-cooled 911.

Despite the company's continual evolution, Singer had never offered a turbocharged restoration. That absence was hardly accidental. Turbocharging represents an entirely different character for the 911, one built less around razor-sharp throttle response and revs than effortless torque, long-legged performance, and the unmistakable visual presence that has long distinguished Porsche's flagship road cars. Bringing that personality into the Singer world would require an entirely new restoration service.

Singer introduced Classic Turbo Services for the 964-generation Porsche 911 in February 2022 before presenting the first completed restoration at the Goodwood Festival of Speed that June. Like every car commissioned through Singer, the process began with a Type 964 donor, though almost every aspect of the car was reconsidered. Newly developed carbon-fiber bodywork paid unmistakable homage to the Type 930 silhouette while refining its proportions and integrating modern aerodynamic concepts. Familiar details remained, yet virtually every surface served a purpose beyond appearance. The distinctive rear-quarter "shark fin" gravel guard became a functional intake feeding cool air to a newly developed twin-turbocharged engine, while the iconic whale tail evolved through extensive engineering, its stylistic reinterpretation remaining immediately familiar.

Mechanical development proved equally comprehensive. At the heart of Classic Turbo restorations sits a 3.8-liter twin-turbocharged evolution of the air-cooled Mezger flat-six, equipped with modern turbocharger technology, air-to-water intercooling, and contemporary engine management. Output debuted at 450 horsepower, with higher-performance specifications available according to each owner's vision. A six-speed manual transmission remains the sole configuration, preserving the direct driver involvement expected of every Singer restoration while delivering all power to the rear wheels. The touring-oriented suspension can be adjusted to suit the personality of the restoration, and an extensive range of bespoke engineering solutions can be considered in collaboration with Singer's Special Wishes team.

The introduction of the Classic Turbo services also broadened Singer's philosophy in meaningful ways. Earlier restorations frequently emphasized immediacy, lightweight construction, and naturally aspirated character. Classic Turbo services-much like the original Type 930 from 1975-embraced a different set of priorities without abandoning the company's meticulous standards. Long-distance touring, remarkable refinement, and everyday usability became central priorities alongside outright performance. Heated power-adjustable seats, air conditioning, navigation, wireless charging, and bespoke luggage could coexist with carbon-ceramic brakes, increased power, and more sporting suspension calibrations. As always, each restoration reflected the preferences of its owner rather than a prescribed specification.

For founder Rob Dickinson, the project carried particular significance. His earliest memories of Porsche centered on a childhood ride in a ur-Turbo, an experience that inspired a lifelong fascination with the marque and ultimately helped shape the company he would establish decades later. Classic Turbo services provided an opportunity to revisit the model that first captured his imagination while applying everything Singer had learned through years of development and collaboration with its clients.

Following its public debut at the Goodwood Festival of Speed, Classic Turbo services immediately became the newest expression of Singer's ever-expanding vision for the air-cooled Porsche 911. Early restorations have remained closely held, with comparatively few appearing on the public market. As one of the earliest vehicles completed under the landmark Classic Turbo restoration services, the vehicle offered here represents a special opportunity to acquire a service that signaled a significant evolution for Singer-one that introduced an entirely new dimension to its already celebrated interpretation of the air-cooled 911.

The "Aurum Verde Commission," internally known as "CT0274," was Singer's international tip of the spear in 2024. Selected in Nice Green Metallic (also referred to as Palm Green Metallic) over a Cognac leather interior with Pascha-style woven leather seat inserts, it was featured in Top Gear and later tested for Evo by journalist and racer Richard Meaden. Meaden was effusive in his five-star review, praising everything from the fit and finish-"the fit of this Palm Green Metallic car's carbon panels is unerringly precise, with a paint finish that's glass smooth and swimming-pool deep"-to its driving dynamics, describing the Classic Turbo services as "one that effortlessly moulds to your mood and works with whatever road you find yourself on." Ultimately, he concluded, "this car has been developed and set up by people who know how a great 911 should feel at and beyond its limit."

This, the very same car Meaden tested, features over $200,000 in optional extras expected from a car of this caliber shown to a worldwide audience in print and digital media. The starting point for any restoration must be the exterior and interior colors, chosen with input from Singer founder Rob Dickinson. The Singer-supplied build sheet, on file and available for review, records that CT0274 received numerous exterior and technical options including Nose Lift, Brembo Brake Calipers in Deviating Finish Pistachio with Carbon Ceramic Rotors, Full Vehicle Paint Protection Film, RSR Fuchs-style Wheels with Black Centers, and an Engine Bay Painted in Exterior Color.

If the exterior established Aurum Verde's identity, the interior completed the vision. Swathed in Cognac leather from the Singer Exclusive Turbo Leather Collection, the optional 8-Way Adjustable Sport Seats, rear seats, and interior side panels feature a Bespoke Pascha-style Weave of Cognac and Lance Watson Anthracite leather. Natural Walnut serves as the Hard Accent Decor Trim on the interior door grab handles, under door pocket trim, across the face of the dashboard, and down the center console that houses a Walnut six-speed shift knob. Satin Bronze Bright Trim highlights many interior components, not least the Floating Gauges and Walnut dashboard trim edges with Mood Lighting. A Premium Audio System and Bone-colored Alcantara headlining round out the richly appointed cockpit.

That same year, the Aurum Verde Commission traveled across Europe visiting Singer's Global Partners. Much like the RUF Yellowbird immortalized in the VHS classic Faszination some 37 years earlier, Aurum Verde starred in Singer's Palm Green Meets the Green Hell filmed at the N�rburgring while undertaking development work supporting T�V certification for Germany and other markets recognizing the standard.
