Some cars make you do the math before you fall for them. This one did the opposite. I saw the paint first, then I read the spec sheet, and only then did I look at the price. Theon Design just turned ten, and it marked the occasion with a 964-based coupe in Oak Green Neo Metallic. It has a carbon body, a 419-horsepower air-cooled flat-six, and a cabin with no screens at all. I have not driven this car, so this is the build and the anniversary, not a drive report. Theon calls it a decade of design and engineering evolution. After ten years of 964s, that sounds about right.
A 964 stripped to its shell
Every Theon starts the same way. The team takes a donor 964, strips it back to its bare shell, and rebuilds it from there. This one is a 35-year-old car, and it took 18 months of work with its UK owner. Each car is a collaboration, not a catalog order. The same one-off logic drives the restomod Defender I covered in April, a $350,000 one-of-one with its own drivetrain.
The bodywork is the headline. The panels, bumpers, and lower sills are F1-grade carbon fibre, made with a composites supplier that works only for Theon. The carbon trims about 661 pounds versus a stock 964. The finished car weighs 2,535 pounds. That is roughly the weight of a modern hot hatch, carrying 419 horsepower. The 964 is the icon here, but the idea travels. The RWB 911 I wrote about earlier this month shows the same hand-built formula on a water-cooled 997.
The chassis got the same treatment. TracTive semi-active dampers work with bespoke spring rates and a steering setup tuned for this car alone. The brakes come from the 993 RS, discs and calipers both. The calipers are painted to match the script on the body. The wheels are 17-inch champagne, on Michelin Pilot Sports with taller sidewalls. The whole setup is tuned for British roads. It has to ride well on rough tarmac, not just corner hard on smooth ones.
419 horsepower, five gears, and nothing to prove
The engine is a rebuilt and remapped 4.0-liter air-cooled flat-six. It makes 419 horsepower and 322 pound-feet of torque. Theon quotes about four seconds to 60 mph. That is quick, but the number is not the point. The point is how it gets there.
Most recent Theon commissions run a close-ratio six-speed built to 993 RS specs. This owner said no thanks. He asked for Porsche’s G50 five-speed instead. Theon says the pairing feels eager on hard roads and relaxed on long ones. Drive-by-wire throttle and selectable engine maps help too. There is a softer town mode for slippery roads and slow traffic. That is the kind of detail that matters when a car like this actually gets used.
The restraint here is the story. Theon did not chase a bigger power number to impress anyone. It kept the car light, kept the gearbox manual, and kept the driver in charge. Next to the 502-hp GT3 Bergsport, this car gives up power and still wins the argument on feel. Porsche’s current 911 range still starts with the same rear-engine idea, just with water cooling and turbos in most trims. That is a choice, and it is the right one for a car like this.
Oak Green, Beechwood, and zero screens
The paint is Oak Green Neo Metallic, Theon’s update of the classic Porsche shade. Champagne script and detailing pick up the wheels and the calipers. It is an old-school color with modern depth. Green 911s have always looked right, and this one is no exception.
Inside, Beechwood semi-aniline and nubuck leather wrap the cabin. Recaro CS seats hold the driver in place. The window switches are milled from aluminum, because Theon sweats that kind of detail. The heating and air conditioning are new and fully electric, so the cabin warms up fast on cold mornings. A hidden MIL-spec wiring loom saves about 55 pounds over the original.
Then there is the thing I keep coming back to. There are no screens anywhere in the cabin. No touchscreen, no digital cluster, no menu to dig through. Just analog gauges, a manual shifter, and the road. Even a base hatchback has a tablet glued to the dash these days. That absence is the loudest feature on the car. It is also the hardest one to fake.
What it costs, and what comes next
This exact car is spoken for. It was built for one UK client, and it is a one-off. If you want your own, Theon Coupe commissions start at £435,000, about $575,000. That is before the donor car, shipping, and taxes, and each build takes 18 months. It is serious money, and it buys a serious car.
The good news is that dreaming is now free. Theon launched its first online configurator for the anniversary. Anyone can spec a Coupe, a Targa, or an R before ever talking to the team. US buyers get local help too, through a concierge service with Humble House. That matters, because the next car in line is the Theon R. It is already in build for its first customer. It will have more than 500 horsepower and a target weight under 2,205 pounds. The Oak Green car is the celebration. The R is the warning shot.
