Mercedes Viano

The Viano is the biggest people carrier from Mercedes-Benz and is based on the Vito van. That's evident in the boxy styling and dated cabin design, but in the back this is designed to be a comfortable and upmarket vehicle - hence its popularity with private hire firms. It comes in three lengths and can carry up to eight adults in plenty of comfort while there's a wide choice of seating variations including individual face-to-face seats.
