You might expect that deadlocks are a given in a car of this calibre, but Mercedes don’t fit them, believing them to be a hindrance to rescuers in the event of an accident. Other than that, safety and security are first class.

Space is in abundance, especially in the limousine. But the boot size may surprise – it’s not as big as you might expect of a car of this size. There’s good stowage though with decent door pockets and a large cubby under the central armrest – however there’s only one cupholder.
