Arvon is the latest one‑of‑one commission from Helderburg, a classic Land Rover Defender 110 Soft Top built as a gift from a client to his wife. Featured by Motor16 in Spain, this build combines British heritage, Porsche‑inspired design, and modern engineering in a way that puts it in the same conversation as bespoke Rolls‑Royce, Bentley, and Maybach commissions.
A $393,000 Defender built to supercar standards
With a final price of 393,000 dollars (around 376,000 euros), Arvon sits well above the cost of a brand‑new Defender OCTA and firmly in supercar territory. Over 3,000 hours of work went into stripping the truck to its last bolt, rebuilding the steel chassis to tighter‑than‑factory tolerances, and applying corrosion‑resistant coatings that the original never received.
Helderburg works exclusively with classic Defenders more than 25 years old, transforming them into unique vehicles that merge British utility with modern, ultra‑luxury execution. Arvon is one of the most ambitious examples to date: a five‑door 110 soft top designed for life between the Hamptons, the beach, and the mountains.
Restoring more than aluminum: structure, rust, and longevity
Motor16 points out a reality that many enthusiasts forget: while classic Land Rover bodies are aluminum and naturally rust‑resistant, the frames, axles, springs, fasteners, hinges, and locks are not. Left stock, those components age poorly, especially in coastal climates and harsh winters.
On Arvon, Helderburg disassembled the Defender to bare components, reworked the chassis with tighter tolerances, and applied anti‑corrosion treatments to the frame and critical hardware. The goal is not just to make the truck beautiful now, but to extend its structural life so it can be used hard and still be standing strong decades from today.
High Pearl Metallic Blue: Porsche‑inspired paint for a Defender
Arvon’s exterior is finished in High Pearl Metallic Blue, a color inspired by early Porsche 356s. The pearlescent finish shifts subtly depending on the light, giving the truck a depth and richness that standard Defender colors simply cannot match.
The bodywork includes a custom front end with a bespoke bumper, new lighting, a hand‑assembled red winch from England, and a Puma hood for a more muscular stance. Widened fender flares, black side steps, reinforced black wheels, and massive mud‑and‑snow tires complete an exterior built for both the beach and the mountains.
Original turbodiesel, rebuilt with no compromises
Unlike many American restomods that swap in modern gasoline V8s or electric powertrains, Arvon retains its original turbodiesel block. Helderburg rebuilt the engine from the crankshaft up and upgraded the cooling system with an oversized intercooler so the Defender can idle indefinitely in direct coastal sunlight.
The choice to keep diesel was driven by real‑world performance: high torque, more efficient consumption, lower cabin temperatures, and better adaptability to sand, snow, and highway cruising. Power figures remain confidential, but both the engine and braking system—with oversized brakes and braided steel lines—have been tuned to deliver a significant improvement in driveability and safety.
A Hamptons‑coastline interior built for real life
Inside, Arvon was designed to evoke the Hamptons coastline rather than a utilitarian farm truck. The seats are upholstered in cream and brown leather with diamond stitching and white contrast, while a two‑tone dashboard (dark brown above, winter white below) frames a modern touchscreen infotainment system with Apple CarPlay and a wood‑wrapped steering wheel.
The custom audio system features high‑end Focal speakers, Italian‑made McConney amplifiers, an Alpine head unit, and a rear subwoofer integrated into a second‑row center console, which now seats two. Classic transverse rear bench seats are retained, allowing the Defender to carry the driver plus seven additional occupants when needed.
Helderburg emphasizes that the leathers used have a high wax content, making them water‑repellent, UV‑resistant, and low‑maintenance with annual conditioning. The result is a cabin that combines luxury, practicality, and durability for everyday use in extreme environments.
Details that reveal thousands of hours of work
A closer look reveals details that justify the 3,000‑hour figure: aluminum door handles, carefully aligned doors, and new aluminum hinges with sintered bronze bearings. Mirror housings finished in body color, an aluminum license plate light bracket with integrated camera, discreet tubular mounts for a high‑lift jack, Fox‑equipped suspension towers, and countless interior touches all speak to the level of craftsmanship involved.
Beyond the multimedia integration, Motor16 highlights the double leather gaiters for the gearshift and transfer levers, and the use of aluminum for nearly every knob and control—right down to the door locks—leaving only the slim body pillars uncovered. It is this obsessive attention to detail that moves Arvon from “expensive SUV” into the realm of rolling artwork.
“As much as a Rolls‑Royce… but more desirable”
Paying €376,000 for an old turbodiesel Defender with a canvas roof, no roll bar, no spare wheel, no tachometer, and no power windows might sound outrageous at first glance. But as Motor16 notes, when you consider today’s labor rates and the 3,000 hours of highly specialized work involved, the price aligns with other coachbuilt, ultra‑low‑volume vehicles.
Their conclusion is clear: this Defender restomod costs as much as a Rolls‑Royce, but they like it more—much more. For Helderburg, Arvon is proof that when a family wants “the ultimate Defender, without compromise,” the result can stand proudly alongside the world’s finest bespoke automobiles.

FAQs about the Motor16 Arvon feature
Why does Motor16 compare Arvon to Rolls‑Royce and other ultra‑luxury brands?
Because Arvon’s price, level of craftsmanship, and one‑of‑one nature place it in the same territory as bespoke Rolls‑Royce, Bentley, and Maybach commissions, rather than typical SUV builds.
How long did it take to build Arvon?
The Helderburg team spent more than 3,000 hours over roughly a year, disassembling the vehicle to the last bolt and rebuilding it with tighter tolerances, anti‑corrosion treatments, and bespoke mechanical and cosmetic upgrades.
Why did Helderburg keep the original turbodiesel instead of swapping a V8?
The original diesel was rebuilt and upgraded for better cooling and drivability, chosen for its torque, efficiency, cabin comfort, and suitability for sand, snow, and highway driving. Motor16 notes that this choice aligns with Helderburg’s philosophy of preserving a Defender’s character while modernizing performance.
Is Arvon meant to be driven daily, or just collected?
Arvon was conceived as a real‑world vehicle, with corrosion protection, high‑wax leathers, durable materials, and engineering aimed at daily use in demanding environments, from coastal humidity to winter roads.
