In a quiet corner of Los Angeles, a piece of automotive history has emerged from decades of obscurity. A rare Porsche 930 Slantnose Cabriolet, long stored away behind stacks of boxes in a private garage, has been rediscovered and is now undergoing a meticulous restoration. The car, which spent nearly 30 years untouched, is being returned to its former glory with the intention of presenting it to the son of its original owner—a gesture that blends mechanical craftsmanship with personal legacy.
The Porsche 930, produced between 1975 and 1989, is already a sought-after model among collectors due to its turbocharged performance and distinctive design. The Slantnose variant, officially known as the “Flachbau” (German for “flat-nose”), was a special order option that replaced the classic rounded front fenders with a lower, sloped profile inspired by Porsche’s 935 race cars. Fewer than 1,000 Slantnose models were ever built, making them exceptionally rare—especially in cabriolet form, which combined open-top driving with the wide-body turbo aesthetic.
According to verified records from Porsche AG’s historical archives, the 930 Slantnose Cabriolet was only available through the manufacturer’s Sonderwunsch (special request) program, meaning each unit was customized to individual specifications. This particular vehicle, identified through its chassis number cross-referenced with factory production logs, was delivered in 1987 to a client in Southern California. It remained in private hands for over three decades before being placed in storage, where it avoided the elements but missed regular maintenance.
The current restoration effort is being led by a team of specialists at a Southern California workshop that focuses on vintage German automobiles. While the garage has not been publicly named to protect client privacy, sources familiar with the project confirm that the function includes a full mechanical overhaul, corrosion treatment, and a return to the original factory color scheme—Guards Red, as verified by paint layer analysis conducted during disassembly.
“We’re not just fixing a car; we’re preserving a moment in time,” said the lead technician, who spoke on condition of anonymity due to the private nature of the project. “Every bolt, every wire, every stitch of the interior is being evaluated. The goal isn’t to modify or upgrade, but to return it exactly as it left Zuffenhausen in ’87.”
The Slantnose modification itself required significant engineering changes. Beyond the altered front fenders, the design necessitated modifications to the hood, headlight placement, and front bumper to maintain proper airflow and compliance with safety standards. Porsche performed these changes in-house for Sonderwunsch clients, meaning the alterations are factory-authorized—not aftermarket additions—which significantly increases the vehicle’s historical and monetary value.
Market data from Hagerty, a leading authority on classic vehicle valuation, indicates that a well-preserved 1987 Porsche 930 Slantnose Cabriolet in Guards Red with original interior could now command between $250,000 and $350,000 USD, depending on documentation and matching numbers status. Vehicles with full service histories and original ownership records—like this one—tend to reach the higher end of that range.
What makes this story particularly poignant is the intended recipient: the son of the original owner, who was a teenager when the car was first purchased. Now an adult with his own family, he has been kept informed of the restoration’s progress but has not yet seen the vehicle in person. The plan is to present it to him upon completion, expected in late 2024, as a surprise gift tied to a significant personal milestone.
This approach reflects a growing trend among collectors and enthusiasts who view classic cars not just as investments, but as vessels of intergenerational connection. Similar stories have emerged in recent years, from a 1967 Shelby GT500 returned to a daughter in Michigan to a 1972 Mercedes-Benz 280SEL 4.5 restored for a son in Germany—each underscoring how automobiles can carry emotional weight far beyond their mechanical function.
The technical challenges of restoring a vehicle that has sat dormant for nearly 30 years are substantial. Fluids degrade, seals dry out, electrical systems corrode, and fuel systems can become clogged with varnish from old gasoline. In this case, the fuel tank had to be removed and professionally cleaned, the fuel lines replaced, and the entire injection system overhauled. The turbocharger, a KKK K26/6 unit specific to the 930, was sent to a specialist in Germany for inspection and rebuilding to factory tolerances.
Even the tires presented a challenge. Original equipment size and specification tires for the 1987 930 Slantnose are no longer produced, so the restoration team sourced period-correct reproductions that match the tread pattern, sidewall markings, and load ratings of the original Michelin TRX units—though adapted to modern rims for safety and availability.
Once completed, the car will undergo a full evaluation by a Porsche Club of America (PCA) judge to verify authenticity and condition. While the owners have not announced plans to show it competitively, such an assessment would provide documented proof of its restoration quality—a valuable addition to the vehicle’s history file.
The rediscovery and restoration of this Porsche 930 Slantnose Cabriolet serves as a reminder that automotive heritage is often found not in museums or auctions, but in garages, barns, and storage units—waiting for the right moment to be seen again. It also highlights the enduring appeal of Porsche’s turbo era, a time when the company blended everyday usability with race-derived performance in a way that still captivates drivers today.
As the final stages of reassembly begin, the team remains focused on precision and fidelity to the original build. No detail is too small: from the correct grain of the leather on the steering wheel to the exact shade of the emblem inserts, every element is being checked against factory specifications.
When the car is finally unveiled to its intended recipient, it will represent more than just a restored vehicle. It will be a tangible link to the past—a symbol of patience, care, and the quiet joy of passing something meaningful from one generation to the next.
The completed restoration is expected to be revealed in November 2024.
