The Porsche Carrera GT is widely regarded as one of the best supercars ever built, perhaps even the greatest of all time. So when a dealership decided to tear apart one unfortunate example and transform it into something entirely different, it understandably raised a few eyebrows. The result is the Miller Motorcars JC9, a one-off creation that reimagines Porsche’s legendary V10 supercar through a very different lens.

The JC9 comes from Connecticut-based Miller Motorcars and was commissioned to celebrate the dealership’s 50th anniversary selling some of the world’s most coveted exotic machinery. Despite its radical transformation, the car hasn’t completely abandoned its Porsche DNA. Its styling is a modern interpretation of the iconic Porsche 917, the Le Mans-winning sports prototype that cemented the brand’s place in endurance-racing history.
Styling: Another Jason Castriota Masterpiece

Responsible for the design of the JC9 is none other than Jason Castriota (shown left), the talented designer behind one-off supercars such as the Ferrari Enzo-based P4/5 by Pininfarina and the C6 Chevrolet Corvette ZR1-based Bertone Mantide. His initials feature in the car’s name, alongside the number nine, signifying this as Castriota’s ninth standout design. His portfolio also includes icons such as the Ferrari 599 GTB, the first-generation Maserati GranTurismo, and even the SSC Tuatara hypercar.
Miller Motorcars says the overall design takes cues from sports prototypes spanning the 1960s through the 1980s, but it’s clear the Porsche 917 was the dominant source of inspiration, particularly the short-tail 917K that won Le Mans in 1970 and again the following year. Some versions of the 917 were tuned to produce well over 1,000 horsepower, enabling them to sprint to 60 mph in under three seconds and reach speeds in excess of 240 mph. Remember, this was back in the 1970s.
Interestingly, Porsche itself explored a modern tribute to the 917 last decade with a concept known as the 917 Living Legend. While a fully functional car was never built, a full-scale clay model was unveiled to the public as part of the 917’s 50th-anniversary celebrations in 2020.

Powertrain: A Manual Gearbox And A Race-Derived V10 Engine

Miller Motorcars has provided very little in the way of specifications, but we do know the car’s body is made almost entirely of carbon fiber and that both the donor car’s 5.7-liter V10 engine and six-speed manual gearbox have been retained. A photo of the interior also reveals the Carrera GT’s signature balsa-wood shift knob remains in place. Porsche originally chose the unusual design to save weight while paying homage to early endurance racers such as the 917, which featured the same distinctive touch.
Assuming no mechanical changes have been made, the V10 should still produce 604 horsepower and 435 pound-feet of torque, while screaming all the way to its 8,400-rpm redline. In the Carrera GT, that output was enough for zero to 60 mph acceleration in just 3.5 seconds and a top speed of 205 mph.

We also don’t have a price. However, with Carrera GT values averaging around $3 million today, it’s safe to assume this one-off creation would command an even steeper premium should it ever be offered for sale.

CarBuzz Insight – Why This Matters
With only 1,270 Carrera GTs ever built, and fewer left after several high-profile crashes, dismantling one borders on sacrilege. For many, the idea alone is enough to trigger a collective wince, especially when the donor car ranks among the most revered supercars of the modern era.
Yet the JC9 earns a measure of respect. It combines one of the greatest analog drivetrains ever made with a striking tribute to Porsche’s racing heritage. We’re sure enthusiasts will either love it or hate it, but regardless, it’s the kind of one-off creation people will still be talking about decades from now, just like Jason Castriota’s other cars.
