I've got an '08 Versa S with the value option package and AT that I bought new in the fall of '07. (I had to get the AT because my wife's been having problems with her knees and can't handle clutch pedals anymore

)
It's been a great car, I haven't had a single problem with it so far. The seats are way more comfortable than any other small car I've tried and there's loads of cargo room, tons of headroom front and back as well. The quality of the materials inside the car is very good and the car is still solid as a rock, no squeaks or rattles at all, even in the cold of winter. It has a very nice if conservative interior and the controls and switchgear have a hefty, positive feel to them. Build quality is good overall, but I have noticed that the Versa's body gaps are a bit wider than you would find on a Honda for example. Except for a couple of small dings, my Versa still looks like new.
What I like most about the Versa is that it doesn't feel or drive like a small, cheap car. The relatively high seating position means you're not looking up at the traffic around you all the time and also makes for very easy ingress and egress, a huge plus if you carry elderly or disabled passengers very often like I do. My only real complaints about the interior are the lame base stereo and the power mirror controls which should be on the door armrest rather than the dash. The stereo's an easy fix, though.
The Versa's admittedly not as much fun to drive as a Honda Fit but it's a lot more comfortable, especially if you're in the back seat. Our Versa's done everything we've expected of it and more, including carrying loads of my daughter's stuff when she moved a few weeks ago. It's a pretty hard vehicle to beat for the price IMO.
