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 completely redesigned luxury SUV that retains the iconic boxy styling of its 1979 predecessor whilst incorporating modern technology and engineering. This all-new generation sheds the downsides of the 40-year-old design whilst embracing the lifestyle appeal that made the original a cult classic. It features a choice of powerful petrol and diesel engines, with AMG variants offering exceptional performance, and combines genuine off-road capability with premium comfort and technology.

Build quality is excellent, with thoughtful design touches that honour the original's heritage, including visible hinges, push-button door handles, and a rear-mounted spare wheel. The cabin is spacious and luxurious, featuring a modern widescreen infotainment system with excellent voice recognition, Apple CarPlay, and Android Auto. Off-road credentials are impressive, with a ladder frame chassis, three locking differentials, rigid rear axle, and low-range gearbox. However, running costs are substantial, with fuel economy ranging from 17.2mpg (G63 AMG) to 26.4mpg (400d), premium insurance, and high servicing costs through Mercedes' official network.

Best for: Affluent buyers seeking a distinctive luxury SUV with genuine off-road capability, those drawn to its iconic retro styling, and drivers who prioritise heritage and exclusivity over economy.

Not ideal for: Budget-conscious buyers, environmentally conscious drivers, those seeking sharp on-road handling comparable to a Porsche Cayenne, or anyone concerned about running costs and emissions.


Comparison vs Key Rivals



The Verdict

You should buy the G-Class if: You're seeking a distinctive luxury SUV with genuine off-road capability, drawn to its iconic retro styling, and prioritise heritage and exclusivity over economy.

Consider alternatives if: You're budget-conscious, environmentally concerned, seeking sharp on-road handling comparable to a Porsche Cayenne, or worried about running costs and emissions.

Competitive Position: The Mercedes-Benz G-Class (2018-present) occupies a unique position in the luxury SUV market, blending heritage styling with modern engineering and genuine off-road prowess. Whilst the Porsche Cayenne offers superior on-road dynamics and the Land Rover Defender provides comparable off-road capability at lower cost, the G-Class stands apart through its distinctive design and uncompromising luxury. It's a heart-over-head purchase that rewards those who value its quirkiness and charm, though running costs are substantial and environmental impact significant. For affluent buyers seeking an unmistakable statement of style and capability, it remains compelling.
