I'm Selling My Mercedes-Benz G500 Cabriolet on Cars & Bids
Doug DeMuro · 2026-09-03
💡 Quick Take
1. Sell your 1999 Mercedes-Benz G500 Cabriolet on Cars & Bids with no reserve if you are no longer using it.
2. Buy an imported power-top G-Wagon Cabriolet if you want an exceptionally rare, highly desirable, open-air luxury off-roader.
3. Choose a V8-powered G-Wagon Cabriolet over the rarer six-cylinder diesel versions for a more robust and sought-after driving experience.
4. Look for a fully federalized and California Air Resources Board (CARB) certified import if you plan to register and drive legally in strict emissions states.
5. Don't buy a convertible SUV expecting stellar fuel economy, as the G500 Cabriolet realistically returns around 13 to 16 miles per gallon.
6. Expect to invest heavily in maintenance and rust remediation, as even well-kept examples like this require significant upkeep over years of ownership.
📊 Detailed Explanation
The speaker is parting ways with his personal 1999 Mercedes-Benz G500 Cabriolet after seven years and nearly 25,000 miles of ownership, listing it on Cars & Bids with no reserve. The decision to sell is driven primarily by changing family dynamics and a lack of use. With three young children under six years old, a small two-door short-wheelbase convertible no longer serves practical family transportation needs. Furthermore, the speaker and his family have gravitated toward fun sports cars like a Porsche 911 Turbo and a Toyota Supra, leaving the G-Wagon sitting idle. He firmly believes that hoarding a rare enthusiast vehicle makes no sense when it is no longer being driven, making it the right time to pass it on to a new custodian.
The Mercedes-Benz G-Wagon Cabriolet with a power-operated soft top is exceptionally rare and desirable. Originally produced from the late 1990s through 2014, only about 2,600 units were ever built. Because these models were never officially sold in North America, acquiring one requires importing it from Europe or Asia—a process the speaker completed in 2019. Crucially, this specific vehicle went through the expensive, time-consuming process of federalization and earned a coveted California Air Resources Board (CARB) sticker in the door jamb. This makes it one of only 10 to 12 fully legal, 50-state compliant imported convertible G-Wagons in existence, bypassing the legal gray areas of out-of-state Montana or South Dakota titling.
Under the hood sits the legendary Mercedes-Benz M113 5.0-liter V8 engine producing around 300 horsepower. Unlike the less powerful six-cylinder and diesel variants produced during its long run, the V8 engine is highly sought after by collectors and enthusiasts. Paired with full-time four-wheel drive, low-range gearing, and three locking differentials, the powertrain offers incredible durability, smooth low-end torque, and rugged off-road capability. Over seven years of ownership, the engine proved completely dead-reliable and required only basic routine maintenance, contrasting sharply with the electronic gremlins and extensive body upkeep common to vintage G-Wagons.
Owning a vintage imported luxury vehicle requires substantial financial commitment, especially to maintain collector-grade condition. The speaker invested over $50,000 in maintenance and repairs during his tenure. This included a massive $20,000 service performed by the renowned U.S. G-Wagon specialists at Nothing But G's in northern Colorado, which tackled necessary rust removal and remediation, suspension replacement, and ignition lock fixes. While minor flaws remain—such as a sticky convertible top catching on the rear headrests, slight wheel scratches, a minor windshield base rust spot, and finicky parking sensors—the car was kept mechanically pristine.
When evaluated against period-correct convertible SUVs of the 1990s—such as the Jeep Wrangler TJ, Suzuki Sidekick, Geo Tracker, and Land Rover Defender—the G500 Cabriolet operates in an entirely different league. While those contemporary off-roaders were notoriously agrarian, loud, and poorly executed, the G-Wagon delivers a bank-vault-like solidity, high-end leather upholstery, heated front seats, air conditioning, and a fully power-operated soft top that transforms it into an effortless all-weather vehicle. It successfully bridges the gap between a rugged, locking-differential-equipped off-roader and an eccentric, exotic-feeling open-air cruiser, ultimately scoring a notable 48 out of 100 on the DougScore.
🎯 Automotive Expert Opinion
Doug DeMuro’s decision to part with his G500 Cabriolet highlights the classic enthusiast dilemma: balancing emotional attachment to an irreplaceable garage queen against the practical reality of zero seat time. From an objective automotive perspective, letting this vehicle go via a no-reserve auction on Cars & Bids is the correct move. Hoarding a rare, highly specialized machine that no longer fits a growing family's daily lifestyle deprives both the collector market and the car itself of fulfilling its true purpose on the open road.
The speaker’s transparent financial disclosure regarding maintenance—specifically noting over $50,000 spent over seven years, including a major $20,000 overhaul by dedicated specialists—serves as a vital cautionary tale for prospective buyers. Vintage Mercedes-Benz G-Wagons are infamous for hidden corrosion and expensive electrical systems. Anyone entering the market for an imported Cabriolet must understand that initial purchase price is only a fraction of the total cost of ownership; professional rust remediation and specialized mechanical servicing are non-negotiable expenses to keep these rare SUVs roadworthy.
Despite the high running costs and notoriously poor fuel economy (averaging 13 to 16 MPG), the G500 Cabriolet represents the absolute pinnacle of open-air utility vehicles from its era. Its combination of a bulletproof M113 V8 engine, triple locking differentials, a power-folding fabric roof, and ultra-low production numbers (around 2,600 units globally) creates an unmatched driving experience. For collectors, the extreme scarcity combined with the exceedingly rare California CARB-legal certification elevates this particular example to an elite tier that standard closed-roof G-Wagons simply cannot match.
Ultimately, the next owner is inheriting a turnkey, meticulously documented icon that requires no immediate major remediation. While the speaker's parting is undeniably filled with nostalgia for beach trips and family memories, his pragmatic exit strategy allows a new enthusiast to experience one of the weirdest, coolest, and most capable luxury convertibles ever built. Buyers entering the auction should bid with confidence knowing the car has been properly vetted and repaired by top-tier specialists, provided they possess the financial fortitude to maintain a vintage European collector vehicle.
