My parents are upgrading from a van to a small SUV.

They want a smaller size, AWD, good gas mileage, and heated seats. They'd like nav system. They want to be able to seat 5 people when needed.

Nissan Rogue:
Decent size: About what they want.
Price was upperend of what they were looking at. Gas mileage was 20/26(Which was the average for what we saw). No nav system.

Nissan Murano:
A bit bigger than the Rogue, much more expensive, nice nav system and options. Gas mileage went down a little

Honda CRV:
So far the winner. Good size, same mpg as most(20/26), nice turn radius, good price(Fully loaded was way below a Rogue with some options) Seated 5 of us comfortably and drove nice. They love the fact that the backseat has 4 cupholders and the front seat has 4.

Subaru Forester:
My mom didn't want to look at it but I pushed her to. I think this is in second right now. Lots of space inside. We haven't had a chance to test drive it yet. Its a bit bigger than they were thinking of(Or at least they think it is) About the same price range as the CRV


Now I don't know how the different AWD systems are. I know Subaru and BMW have similar systems and are on top. I don't know how Honda or Nissans is at all though.
Talk to me about each of these different ones. We haven't had a chance to go to the Toyota, Mazda or the Jeep dealerships yet. What other cars should we look at?
