I've had mine for 6 months now, and I'd say yes....maybe....
I'll elaborate. I'm 6' 5" and obviously need the drivers seat fully back on the runners. This leaves *just about* room for either of my kids (5 & 7) to go behind my seat. You wouldn't fit an adult in comfortably with the seat fully back, but you can squeeze one in at a push.
Having said that, if a "normal" person drives it (my wife) and has the seat a bit closer to the wheel, then 2 adults will fit in the back in relative comfort.
Hope that helps a bit?
If I were you, I'd pop into the dealer and have a sit in it!
