Mercedes-Benz G-Class 2018-2024 Ultimate Buyer’s Guide

The Mercedes-Benz G-Class, affectionately known as the G-Wagon, stands as an automotive icon blending military-grade toughness with opulent luxury. The second-generation model, produced from 2018 to 2024, refined this legendary formula, offering superior on-road dynamics while preserving its unrivaled off-road prowess. This guide delves into what makes these used models compelling choices, despite their premium price tags and running costs.

Iconic Heritage and Modern Evolution

Originating in the late 1970s as a rugged military vehicle under the W460 designation, the G-Class evolved through decades of minimal changes until the W463 arrived in 1990. The 2018 refresh marked a pivotal update, enhancing refinement without diluting its boxy, aggressive silhouette. This Mk2 version addressed past criticisms of ponderous handling, incorporating advanced suspension and chassis tweaks for better composure on tarmac.

Buyers today find a vehicle that commands attention, with over 200 used examples available in recent listings, spanning diesel and petrol variants. Its enduring appeal stems from a reputation for bulletproof durability and status-symbol cachet, making it a staple for celebrities and adventurers alike.

Market Pricing and Value Retention

Used G-Class Mk2 models hold value exceptionally well, reflecting their desirability. Entry-level prices start around £90,000 for higher-mileage diesels, climbing to £170,000 for low-mileage petrol AMGs. A sweet spot emerges around £95,000-£100,000 for 2019 G350d models with 30,000-40,000 miles, balancing affordability and condition.

Diesels represent about one-sixth of listings and offer the best entry points, while petrol V8s command premiums for their thunderous performance. Expect depreciation to be minimal, with well-maintained examples retaining 70-80% of original value after five years.

Engine Options and Performance Breakdown

The 2018-2024 lineup featured robust powertrains suited to the G-Class’s 2.5-tonne heft. Diesel options included the G350d and G400d, both powered by the OM656 3.0-liter inline-six, delivering 282-330 hp with torque figures exceeding 440 lb-ft for effortless towing up to 3,500 kg.

• G350d: 282 hp, 0-62 mph in 7.4 seconds, 26-30 mpg combined.
• G400d: 330 hp, 0-62 mph in 6.4 seconds, similar efficiency.
• G500/G550: 4.0-liter biturbo V8, 416 hp, 5.4 seconds to 62 mph, 20-22 mpg.
• G63 AMG: 577 hp V8, 4.2 seconds, explosive acceleration but thirstier at 18 mpg.

All pair with a slick nine-speed automatic and permanent 4Matic all-wheel drive, featuring three locking differentials for extreme off-road capability. On-road, adaptive damping transforms the ride, smoothing potholes and stabilizing high-speed cruising despite the upright stance.

Luxury Interior and Packed Specifications

Step inside, and the G-Class reveals a high-tech haven far removed from its utilitarian roots. Twin 12.3-inch digital screens dominate the dashboard, powering the MBUX infotainment with voice control, navigation, and a 16-speaker Burmester audio system. AMG Line Premium Plus spec, standard on diesels, includes Nappa leather, heated/ventilated seats front and rear, three-zone climate, matrix LEDs, 360-camera, and a panoramic sunroof.

AMG models amp up the sportiness with larger alloys, performance brakes, and exclusive trims. Practicality shines with 667 liters of boot space (expandable to 1,946 liters), though the side-hinged tailgate can be cumbersome in urban settings. Five passengers fit comfortably, with superb visibility from the elevated seating position.

Off-Road Supremacy Meets On-Road Refinement

True to its heritage, the G-Class conquers terrain with ladder-frame chassis, solid axles, and 9.5 inches of ground clearance. Features like trailer stabilization and low-range gearing make it a towing champion, ideal for caravans or heavy loads.

Surprisingly agile on twisties, thanks to widened tracks and refined geometry, it rivals luxury SUVs in comfort. Wind noise is minimal, and the cabin remains serene at motorway speeds, underscoring Mercedes’ engineering mastery.

Reliability Insights and Maintenance Realities

Mercedes G-Class models from this era boast strong reliability, with chain-driven engines eliminating cambelt worries. Service intervals are 12 months/12,500 miles, costing £525 for minor (oil/filter) and £650 for major services, plus £500 every fourth for rear axle oil.

Common issues are few: watch for electrical gremlins in early MBUX units and ensure transfer case oil changes. Recalls have targeted minor items like fuel lines; always check via VIN. High running costs—insurance, tires, and fuel—reflect its premium positioning, but longevity offsets this for diligent owners.

What to Inspect Before Purchase

Prioritize full service history, as neglect amplifies costs. Key checks:

• Undercarriage for off-road damage or corrosion.
• Diff and transfer case fluid condition.
• Wheel alignment and suspension bushes.
• Digital cluster functionality and software updates.
• Towing hitch integrity if applicable.

Test drive across varied surfaces to verify smooth shifts and damping. Low-mileage examples often indicate garage queens, but verify with MOT history.

Comparing G-Class to Rivals

The G-Class excels in prestige and dual-purpose versatility, outshining rivals in status but trailing in outright value.

Ownership Costs and Budgeting Tips

Annual costs can exceed £5,000, driven by £1,500+ insurance, £300 tires, and premium fuel. Budget for specialist servicing outside main dealers to save 20-30%. Warranties covering up to 100,000 miles mitigate risks on high-value purchases.
