Whether a Opel Mokka B 1.2 DI Turbo Ultimate is a useful automobile for families, is not easy to answer from a technical point of view. families pay attention to a wide range of things when buying a new cars, so this consideration only considers the common aspects.
The Opel Mokka brings 5 seats with it which is basically good and sufficient for many families, but the car fluffs when it comes to the trunk - 1105 liters of volume might not be sufficient for most families. There are no Isofix brackets installed. These could be used to secure child seats easily and safely, via airbag deactivation, babies and small children could be carried along in corresponding seats against the direction of travel on the front passenger seat - however, this function is unfortunately not available on this car.
