My husband has a 13 Focus sedan. I don't know how similar the back seats are between the sedan and hatch, but with two kids it's no problem at all. I can do three across when needed. That was my only stipulation for his car, that three across was possible. It does require the correct combination of seats. It puts the baby in the middle which is literally a pain in my back to load her since there are seats in the outboard positions, and the booster kid can't buckle herself, so it's not pleasant but it is doable. When not doing three across I have not come into anything unusual when installing. I haven't even needed to twist buckle stalks and I have Radians. No weird plastic hinges, no rigid forward-leaning buckles. Oh, head restraints are removable and the outboard ones aren't terribly forward-leaning so I can leave them on if I want.
It's not my daily driver so I'm still not fully used to the dash layout. I almost ran it out of gas a couple weeks ago because of that. I don't know why I thought "full" would be at the bottom of the gauge but thankfully the idiot light and ding warned me in plenty of time. The Sync (Bluetooth) is really nice. I can connect my phone and start up Pandora without taking my hands off the steering wheel. I know DH uses the voice activated controls a lot. I have not gotten them to work but I haven't really tried, either.
His commute is about ten minutes city driving, twenty minutes highway and he gets 38 mpg.
