Asking whether a Mazda MX-30 DR e-SKYACTIV First Edition is a good automobile for families, is not easy to answer from a technical point of view. families have a wide range of requirements, so this consideration only considers the common aspects.
The Mazda MX-30 brings 5 seats with it which is basically good and sufficient for many families, but the car fluffs when it comes to the trunk - 1171 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.
