Asking whether a Fiat 500X 334 Dolcevita 1.0 Firefly Turbo Launch Edition is a suitable automobile for families, is not easy to answer from a technical point of view. The range of families requirements is wide, so this consideration only considers the common aspects.
The Fiat 500X brings 5 seats with it which is basically good and sufficient for many families, but the car fluffs when it comes to the trunk - 1000 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.
