I say, yes it’s very well-suited as a family car. It holds 4 people comfortably and still has a decent amount of luggage room.
Additionally, when you fold down the back
seat, you have a tremendous cargo volume. Below is a photo of when I helped our daughter move. One of the nice things is the length of item you can put in the back. I once folded down the seats and transported a 6’ high bookcase in the back with the hatch closed.
This is all assuming that you don’t mind using your sport sedan as a pickup truck occasionally.
