  • Larger engine means higher costs
  • Strong resale values expected

Without the 2.0-litre diesel options available in the normal E-Class Estate, you will have to dig deeper to run an All-Terrain. Not only will list prices and finance figures be higher – with a starting price of around £50,000 – but you’ll spend much more on fuel too.

Claimed fuel economy for the 3.0-litre diesel is likely to stand just below the 50mpg mark, meaning more frequent trips to fill up than with the Estate equivalent. Servicing could also be pricier with the addition of the all-wheel drive system.

Mercedes residual values are usually strong, and there's no reason to expect otherwise here. The off-roader styling might limit the All-Terrain's appeal, but we think values will remain strong in the used market.

With no economy-focused 2.0-litre diesel engines available in the All-Terrain – and the addition of four-wheel drive – this model has worse eco-credentials than the standard E-Class Estate.

Emissions are likely to come in around the 160g/km mark, which is high for a Mercedes estate, but still lower than many large off-roaders. Stick with the standard 19-inch alloy wheels for the lowest emissions, as the hefty 20-inch offerings make the car emit more. 

Mercedes has a reputation for making long-lasting cars and build quality on the E-Class All-Terrain makes it feel like it has been built to last too. Mercedes has worked hard over recent years to boost the reliability of its cars, however, some of its models haven’t lived up to the high standard set by the brand’s high pricing.

With the addition of a complex all-wheel drive system there is more to go wrong on the All-Terrain than the standard car, though there haven’t been any major recalls recently for the previous model. Therefore, it should prove a reasonably reliable vehicle.

Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.
