Yes.
I just google'd and found plenty. But, you said you searched, OK. For future reference, try to polish your search skills.

+1 to both of these.As said before, yes there is a backseat in a hatch.
But if your passengers are 5'8" or taller, it's a no-go. If you have children, and they require a car-seat; it's a no-go.
Not a whole lot of room back there. It's not the worst I've seen, but it's not that great. Just keep it in your head that it's got two front seats, and lots of 'cargo room' in the 'back seat'. The back seat is only good for emergency purposes only for transporting people.
And that's my $.02
