As you’d expect, the Merc has a huge boot. Our practicality testers found room for all their luggage, with space to spare.
Our test drivers were equally impressed. The 3.0-litre diesel is an absolute monster, albeit well mannered.
With 516lb ft of torque, the All Terrain tows from 30 – 60mph in 6.2 seconds. But the engine is very quiet.
Brute-in-a-suit performance is matched to textbook stability.
However, the All Terrain is expensive to buy, and that amazing engine has a very real thirst for fuel.
