Size
I have 3 kids and tbh I can see this even being a squeeze on long journeys.
The fact the ST doesn't come in a 5 door is daft IMO, especially when it's a 5 door in the states.
I do like the new fiesta ST and tbh it probably offers more performance and a hotter drive (plus i've always tinkered with cars so Mountune would be done) but I need to grow up a bit now haha
The Focus ST was the other option but cost more and again didn't seem to be that big in the rear compared to this. Boot size is bigger on the Cee'd too. Insurance for the Cee'd is £380 odd, with the Focus that jumped to £500+
