EMC’s Approach to the Vintage Cabrio G Wagon
Since 2017, Expedition Motor Company has focused on one platform: the Mercedes-Benz 250GD Wolf. Originally built as a short-wheelbase military Geländewagen, the 250GD is the foundation of every build we produce. We source vehicles directly from militaries across the globe, disassemble them completely, and rebuild each one from the frame up in our manufacturing facility. Every system, including engine, chassis, suspension, brakes, electrical, and interior, is handled in-house by our team of 26. Nothing is outsourced.
Over more than 175 completed builds, each truck has informed the next. Engineering decisions refined over time carry forward into everything we build today.
The Platform
The 250GD Wolf began as a purpose-built military vehicle, designed to operate in extreme conditions over difficult terrain with minimal maintenance and maximum reliability. The result was a body-on-frame, short-wheelbase utility truck with a naturally aspirated diesel engine, mechanical four-wheel drive, and differential locks, built to last in ways that most vehicles are not.
As a two door g wagon in the truest sense, the 250GD was originally a short-wheelbase, open-top vehicle built without the added complexity of the civilian variants. The convertible G Wagon that EMC restores occupies a specific and increasingly rare category. It is not a modified modern G-Class but a restored original from the early 1990s, rebuilt to a standard it never had from the factory. What makes the vintage convertible Mercedes appealing is precisely what made it a credible military vehicle: the simplicity of its structure, the directness of its drivetrain, and the durability of its components. Those qualities do not require reinvention. They require preservation and refinement.
A Long-Term Program, Not a Fixed Product
We track our builds by generation, V1 through V6, with each generation reflecting substantive changes to how we approach the restoration rather than cosmetic updates. Suspension geometry, drivetrain integration, acoustic treatment, interior design, HVAC packaging, and electrical architecture have all been developed and refined across generations, such that a V6 build is a meaningfully more developed vehicle than a V1 was.
Early builds established the baseline: a complete frame-off restoration with period-correct specification and tailored exterior and interior choices. As the program developed, we began addressing the platform in more systematic ways, examining ride quality, braking performance, and interior usability as connected systems rather than isolated components. Proprietary suspension packages were developed and tested across multiple builds before being standardized. HVAC and electrical architecture were redesigned from scratch to integrate modern components in a way that fits the original cabin structure without compromising its character.
Each current V6 (version 6) requires over 2,500 man-hours of work from start to finish, a figure that has grown with each generation as the scope of what we address has expanded. The vehicles that leave our facility today are the product of nearly a decade of continuous development on a single platform. We do not view the EMC Wolf as a finalized product, but as an ongoing project.
What We Change, and What We Don't
As a classic Mercedes convertible, the vintage cabrio G carries a distinct kind of appeal, one rooted in equal parts utility, luxury, and analog character. Our approach is to refine the Wolf for modern use without altering what makes it distinctive. We address the systems that genuinely needed improvement: suspension rebuilt with proprietary components from Bilstein, Eibach, or Fox, configured specifically for the 250GD chassis; braking upgraded to AMG-spec hardware; cooling systems redesigned for the demands of upgraded engines; and sound insulation added strategically throughout the cabin to reduce harshness over long distances without eliminating the mechanical feel of the vehicle. Every build includes wireless Apple CarPlay, a Harman premium sound system, heated seats, front and rear charging ports, and a Vintage Air A/C unit integrated into our redesigned dash structure.
We leave intact what does not need changing. You will not find illuminated badges or bright seatbelt color options. The proportions of the vehicle are also not altered. The soft-top configuration, which is central to what makes the convertible g wagon distinctive, is retained and offered in three formats: full soft top, bimini, and bikini. The finished vehicle drives far better than the original and is more comfortable day-to-day, while still feeling like a Wolf.
Engine Options
We offer four engine configurations, each developed and integrated in-house to provide our clients multiple options based on their vision for the EMC Wolf.
The OM602 is the naturally aspirated 2.5-liter five-cylinder diesel the 250GD was originally built around. Mechanically simple, long-lived, and authentic, it remains the right choice for clients who want the closest approximation of the original driving experience. Each engine is fully rebuilt before installation, with all wear components replaced and clearances set to factory specification.
The OM605a and OM606a are turbocharged progressions of the same Mercedes-Benz diesel family. The OM605a produces far more torque than the naturally aspirated OM602, making the Wolf capable at highway speeds without significantly changing its character, while the OM606a takes that further with additional power and refinement. Both engines are paired with either a five-speed manual transmission or an 8HP 8-speed automatic.
The LS3 V8 is a different proposition entirely: 430 horsepower paired with a six-speed automatic transmission. Integrating a GM V8 into the 250GD chassis required significant development work across mounting points, driveline geometry, cooling capacity, and engine management systems, all engineered specifically for this application. The objective was a finished vehicle that felt factory-cohesive rather than modified. Clients who choose the LS3 get a convertible g wagon with the analog character of the original platform and the performance of a modern 6.2-liter V8.

Interior and Materials
The interior of an EMC Wolf is designed around the reality of how the vehicle gets used. The 250GD is an open-top truck driven in varied conditions, parked near the beach, and used the way vehicles should be used. We utilize weatherproof upholstery across all builds, engineered for durability and cleanability, holding up under sun exposure, humidity, and the demands of open-air driving. Wood trim options, including AAA European Oak in multiple finishes, are available as accent elements, and seat configurations vary by build with options allowing for up to eight passengers.
Modern convenience features are integrated discreetly throughout the cabin. The interior reads as a functional, considered space rather than a retrofit.
175 Builds Later
More than 175 EMC Wolfs have been completed and delivered since 2017, each one built entirely in our facility by our team of craftsmen. The program continues, and each build we complete becomes part of the foundation for the next.
