The M-Class received a five-star crash safety rating from Euro NCAP which is the maximum rating available. As well as dual front, side and window airbags, ABS with brake assist, electronic stability programme, anti-skid control and seatbelt pre-tensioners, it also comes with ‘Pre-Safe’. This system senses that the car may be about to be involved in a accident and prepares the key safety systems for a possible collision – the seatbelts are tightened, it moves the seats into a better position and closes the sunroof if the car is about to roll.

Security features include an alarm, immobiliser and remote central locking.

The M-Class adapts well to family life. The boot’s a good size, the rear seats have a 60/40 split and they can be folded down too (removable cushions can be specified for a flat load area). There’s a total of 2,012 litres of storage space and enough room for items up 2.10 metres in length. Although the glovebox contains the CD autochanger, it doesn’t mean less storage space.

The changer is hidden in the roof of the glovebox and drops down at the press of a button. However, unlike the last M-Class, there’s no seven-seat option for this model – you’ll need to go for the more expensive GL model or consider an Audi Q7 or BMW X5.
