I have the 3rd row seats, and wish I'd passed.

They're probably the right size for an under 6 year old, but that's about it. The only way we were able to fit an adult back there was sitting sideways in one seat with their feet in the other.

The center console between the seats precludes lying down in them, if you were diminutive enough to fit...

I'd rather the spare, and the jack. Now I know.
