Life with a G-Class is expensive even before you’ve left the Mercedes showroom, so the running costs are unlikely to come as a shock. That said in an age of electric vehicles and hybrids, the G still feels like a bit of a dinosaur. A loveable dinosaur, but prehistoric all the same. 

The G 400 d starts from a not insignificant £131,000, but the G 63 weighs in close to £175,000. And the costs won’t stop there.

In the G 400 d, you could expect around 21mpg depending on wheels and options, but in the G 63 the economy drops as low as 15mpg. Neither versions are what you’d call efficient, but the G-Class wasn’t built with aerodynamics and efficiency in mind. High CO2 emissions make the G-Class tax inefficient for private and company car users.

Insurance groups

Make sure you’re sitting down when you use a price comparison site for the G-Class insurance, because the cost is likely to be very high. While the grouping for the G 350 d hasn’t been announced, the G 63 slots into group 50 – the highest rating. This places it alongside supercars and luxury cars.

Depreciation

Depreciation is unlikely to bother a G-Class owner, and because sales in the UK are likely to be modest, there’s unlikely to be an oversupply of used vehicles. The cult status also helps with residual values, which are in the region of 60 per cent, making the G-Class one of the best performers on the market. However, when a new car costs close to £130,000, the immediate hit is still quite severe.
