Seat Leon FR with 18″ family-friendly?

Hello, after I had actually shot myself at a Ford Focus Titanium 1.6l Ecoboost (150hp), I became skeptical about my visit to the Seat dealer today and now prefer the Seat Leon FR 1.4 TSI (140hp). Unfortunately, there is no demonstration vehicle available in the area as FR and I’m a little skeptical about whether the FR with a sports car and 18″ might be too hard to transport our little daughter (6weeks). What are your impressions? H abe read that the Leon druch is a bit bumpy. Now I have also considered the Golf 7 in the meantime, although it leaves me emotionally cold. I am grateful for every opinion. Greeting Daniel
