I have an 07 Civic Si, which I think is perfect for our situation. I don't haul big things around (for that we have a truck

) but if I need the extra space, the seats fold down and it really serves as my multipurpose car.

You know what's funny? I purposely put Kaji in the backseat most of the time
because the windows are smaller. He stresses easily and if he can't see, he has nothing to freak out about and will settle down.
If I put Kaji's car seat in the front, the airbags automatically shut off. (not enough weight in the seat) I think as long as you upgrade to a newer model of any car (I'm thinking 06 and beyond) that feature will exist. I'll ask bf if his 06 Mustang GT has that feature, I can't remember. But I'm sure you can add that as a feature you want in a future car for Zoe's safety and your human passenger's safety.
