Mercedes-Benz G-Class (2018-present) Pros and Cons

Pros	Cons
Amazing to drive off road	Hugely expensive to buy and run
Eye-catching retro styling	Very high emissions
Luxurious cabin with space for five and their luggage	Not as sharp to drive as a Porsche Cayenne

Quick Summary

The Mercedes-Benz G-Class (2018-present) is a luxury SUV that retains the iconic boxy styling of its 1979 predecessor whilst being completely redesigned underneath. This modern iteration combines rugged off-road capability with contemporary luxury and technology, featuring a choice of powerful petrol and diesel engines, with AMG variants offering exceptional performance. The cabin is well-appointed with a modern widescreen infotainment system, Apple CarPlay, Android Auto, and impressive voice recognition, all whilst maintaining charming retro touches like push-button door handles and visible hinges.

Off-road, the G-Class is genuinely capable with a ladder frame chassis, three locking differentials, rigid rear axle, low-range gearbox, and impressive approach, departure, and breakover angles. On-road, it's far more refined than its predecessor, offering comfortable ride quality and responsive steering, though it lacks the sharpness of a Porsche Cayenne. However, running costs are substantial, with fuel economy ranging from 25.9mpg to 26.4mpg for diesels and 17.2mpg for the G63 AMG. Vehicle Excise Duty is £490 annually, insurance sits in the top 50 groups, and official Mercedes servicing is essential to maintain resale value.

Best for: Wealthy buyers seeking a distinctive luxury SUV with genuine off-road credentials, those who value retro styling combined with modern technology, and enthusiasts willing to embrace a heart-over-head purchase.

Not ideal for: Budget-conscious buyers, environmentally conscious drivers, those prioritising on-road handling dynamics, or anyone concerned about high running costs and emissions.


Comparison vs Key Rivals



The Verdict

You should buy the G-Class if: You're a wealthy buyer seeking a distinctive luxury SUV with genuine off-road credentials, value retro styling combined with modern technology, or want a heart-over-head purchase that stands out.

Consider alternatives if: You're budget-conscious, environmentally concerned, prioritise on-road handling dynamics, or worry about high running costs and emissions.

Competitive Position: The Mercedes-Benz G-Class (2018-present) occupies a unique position in the luxury SUV market, blending iconic retro design with contemporary engineering and technology. Whilst rivals like the Porsche Cayenne offer sharper on-road handling and the Land Rover Defender provides similar off-road capability at lower cost, the G-Class delivers unmatched style and presence. Its luxurious cabin, impressive off-road credentials, and improved on-road refinement justify its premium positioning for discerning buyers willing to embrace its substantial running costs. It's a statement purchase rather than a practical choice, appealing to those who value exclusivity and heritage alongside modern comfort and capability.
