The Helderburg Sandoval 110: A Custom Land Rover Defender Masterpiece

“I’ve always been drawn to the timeless classics—the things that don’t need to prove themselves, that simply are. Helderburg is built on that same principle: timeless, functional, and crafted with an understanding that the best things in life are those that remain true to themselves, no matter the passing trends.”

The world of custom Land Rover Defenders is filled with unique builds and eye-catching designs, but few stand out quite like the Helderburg Sandoval 110. This meticulously crafted vehicle represents the pinnacle of custom Defender craftsmanship, combining classic styling with modern performance and luxurious amenities. Let’s delve into the details of this remarkable custom Defender and explore what makes it so special.

The Helderburg Legacy

Helderburg, a renowned custom Land Rover Defender builder, has established a reputation for creating some of the most sought-after and visually striking Defenders in the world. The Sandoval 110 is a prime example of their expertise, following in the footsteps of other popular builds like Bruno the 110 and Enzo the D130.

Sandoval’s story begins in 1997 when it originally arrived from France. Since then, it has undergone a complete ground-up restoration, transforming it into the stunning vehicle we see today. This process involved a meticulous rebuild, starting from the frame and working up, ensuring every component meets Helderburg’s exacting standards.

Exterior Design and Color

One of the most striking features of the Sandoval 110 is its unique color. Described as close to Willow Green, the paint job incorporates a fine metallic finish with bronze undertones. This custom color creates a mesmerizing effect that changes depending on the lighting conditions.

In direct sunlight, the Sandoval exhibits a bronzy green hue with visible metallic flakes. However, in the shade, it transforms into a green with subtle bronze undertones. This color-shifting effect adds depth and character to the vehicle, making it truly stand out from other custom Defenders.

The exterior design is further enhanced by several key features:

  • Puma Bonnet: The raised Puma-style bonnet gives the Sandoval a more aggressive and rugged appearance.
  • Custom Grille: A handmade metal grille from Germany adds a utilitarian touch, allowing visibility of the fan behind it.
  • Signature Headlights: LED headlights with a distinctive broken beam pattern and smoked turn signals create a unique front-end look.
  • Hand-cut Louvers: While serving no functional purpose, these louvers on the bonnet add a classic touch reminiscent of vintage Bugattis, Jaguars, and Bentleys.
  • Full Roll Cage and Roof Rack: These additions not only increase functionality but also contribute to the vehicle’s adventurous aesthetic.

Performance Upgrades

The Sandoval 110 is not just about looks; it’s built to perform. Helderburg has made significant upgrades to the drivetrain and suspension to ensure this Defender can handle any terrain with ease.

Engine and Transmission

At the heart of the Sandoval is a performance-tuned 300 TDI engine. This powerplant has been extensively modified to increase both power and efficiency:

  • Full-width intercooler for improved cooling
  • Custom injection pump for optimized fuel delivery
  • 3-inch stainless steel exhaust system for better flow and a more aggressive sound
  • VNT turbocharger for improved responsiveness
  • Custom ported and polished cylinder head to increase low-end and mid-range torque while reducing noise

The transmission is a rebuilt 5-speed manual, with the fifth gear serving as an overdrive for improved highway efficiency. Both front and rear differentials have been replaced with units featuring the correct ratio for the vehicle’s lift, ensuring the speedometer remains accurate.

Suspension and Brakes

To improve the Sandoval’s off-road capabilities and on-road comfort, Helderburg has installed a comprehensive suspension upgrade:

  • Approximately 3-inch lift
  • Fox suspension components
  • Proper radius arms to accommodate the lift and prevent premature wear

The braking system has also been upgraded to handle the increased weight of the vehicle:

  • 6-piston brake calipers in the front
  • 4-piston brake calipers in the rear

These larger brakes ensure the Sandoval can come to a stop quickly and safely, despite its considerable weight of over 6,000 pounds.

Interior Comfort and Design

The interior of the Sandoval 110 is where Helderburg’s attention to detail truly shines. The cabin exudes a sophisticated ambiance reminiscent of an English library or a high-end cigar bar.

Color Scheme and Materials

The interior features a carefully curated color palette:

  • Black leather with a subtle gray undertone
  • Rich brown accents
  • Caramel-colored stitching for contrast
  • Chocolate brown Italian Alcantara headliner

This combination creates a warm, inviting space that balances luxury with the Defender’s rugged heritage.

Seating Configuration

The Sandoval offers a versatile seating arrangement:

  • Front row: Two bucket seats
  • Second row: Foldable bucket seats that can accommodate two passengers
  • Rear cargo area: Two inward-facing bench seats

The rear cargo area setup is particularly noteworthy. Instead of traditional rear-facing seats, the inward-facing benches provide a more social seating arrangement while maximizing cargo space. This configuration is popular among owners who enjoy using their Defenders for group outings or adventures.

Climate Control and Insulation

Despite its classic roots, the Sandoval 110 offers modern comfort. The vehicle has been thoroughly insulated to improve climate control efficiency. The air conditioning system, primarily located in the front, is capable of cooling the entire cabin, including the rear cargo area, given enough time.

Off-Road Capability

While the Sandoval 110 is undoubtedly luxurious, it hasn’t forgotten its off-road heritage. Several features enhance its ability to tackle challenging terrain:

  • Beadlock-style wheels with heavy-duty off-road tires (likely STT Pro)
  • Rock sliders made of thick metal to protect the body during off-road excursions
  • Wider wheel arches to accommodate the larger wheels and tires while minimizing mud and gravel spray
  • NAS-style rear bumper with a built-in receiver hitch and step for easy access to the cargo area

These additions ensure that the Sandoval is as capable on the trail as it is stylish on the street.

The Helderburg Touch

What sets Helderburg apart from other custom Defender builders is their obsessive attention to detail and commitment to quality. Every aspect of the Sandoval 110, from the custom color to the hand-picked interior materials, has been carefully considered and expertly executed.

The company’s philosophy seems to be centered around creating vehicles that are not just modes of transportation, but experiences in themselves. This is evident in the way Paul, the Helderburg representative, describes how people interact with the vehicle. From friends wanting to climb the rear ladder to couples preferring to ride in the rear-facing seats, the Sandoval 110 is designed to create memorable moments.

Customization Options

While the Sandoval 110 represents a specific build, Helderburg offers a range of customization options for clients looking to create their own unique Defender. Some of the choices available include:

  • Three seats or two seats with a center cubby in the second row
  • Sliding or fixed windows in the cargo area
  • Different wheel and tire combinations
  • Various exterior color options
  • Custom interior color schemes and materials

This level of customization allows each Helderburg to be tailored to its owner’s specific tastes and needs.

The Appeal of Custom Defenders

The popularity of vehicles like the Sandoval 110 speaks to a growing trend in the automotive world. As mass-produced vehicles become increasingly similar, there’s a rising demand for unique, personalized vehicles that stand out from the crowd.

Custom Defenders like the Sandoval offer a perfect blend of classic styling, modern performance, and bespoke craftsmanship. They appeal to enthusiasts who appreciate the Defender’s iconic design but desire something more refined and personalized than a stock model.

Moreover, these custom builds often become more than just vehicles; they’re rolling works of art that capture attention wherever they go. The Sandoval’s unique color, for instance, has been known to draw crowds at shows, with people clamoring to take pictures and marveling at its distinctive hue.

Conclusion

The Helderburg Sandoval 110 represents the pinnacle of custom Land Rover Defender builds. It seamlessly blends classic Defender ruggedness with modern luxury and performance, creating a vehicle that’s as capable on rough terrain as it is turning heads on city streets.

From its mesmerizing color-shifting paint to its meticulously crafted interior, every aspect of the Sandoval has been carefully considered and expertly executed. It’s a testament to Helderburg’s skill and vision, showcasing what’s possible when passionate craftsmen apply their expertise to an iconic vehicle platform.

For those in the market for a truly unique vehicle that combines heritage, luxury, and capability, custom Defenders like the Sandoval 110 offer an compelling option. They provide an opportunity to own a piece of automotive art that’s not just a mode of transportation, but a statement of personal style and appreciation for fine craftsmanship.

As the automotive world continues to evolve, with an increasing focus on electric and autonomous vehicles, custom builds like the Sandoval 110 serve as a reminder of the enduring appeal of hands-on, bespoke vehicle creation. They celebrate the art of automotive design and the joy of driving, ensuring that even in an age of high-tech transportation, there’s still room for vehicles that prioritize character, style, and the pure pleasure of the open road.

Every line above is the result of upgrades engineered in-house, found in no other custom or restomod Defender in the world.

My Journey with Classic Land Rover Defenders

Four Styles, One Custom Process

A Helderburg is not one look. It is your own.

Sandoval is one direction. Every Helderburg is custom, designed around the owner rather than chosen from a catalogue, and most commissions draw from one or two of these four. The expedition build is the one most people picture first. It is only the beginning of what a custom Defender by Helderburg can be.

Why a Helderburg Drives Differently

The difference is not cosmetic alone.

The architecture itself has been re-engineered. If you want the full picture of what is under a Helderburg before you speak to Paul, two doorways.

The Twelve Systems

Sandoval carries twelve proprietary Helderburg systems, found in no other restored, custom or restomod Defender. The drivetrain on the original block. A suspension with the body roll engineered out, widened at the chassis, not with spacers. A cabin built for the eighth hour, not the first.

See Helderburg's Proprietary Upgrades →

Three Approaches. Only one is a Helderburg.

A classic Defender can be restored, restomodded, or re-engineered. A restomod replaces the body and drops in a GM V8 crate motor, no longer numbers matching. Respectfully, a kit car. A Helderburg keeps the original chassis and block, and re-engineers everything else.
