my stepfather used to have a forrester - personally I hated it. But couldnt fault the grip...
This is a very different beastie - its more of a workhorse, less of a drop-the-kids-off-at-school look and feel.
The 4WD system in the nav' has a locked centre diff, making hard cornering very hard work in the dry (the wheels turn at different speeds in hard cornering (as in parking type manuvers) and the fixed front back ratio causes wheel hop / skip)
But - conversely, this makes for better off road grip.
The nav has much worse turning circle.
The nav can carry a LOT more.
The nav cruise control is a lot better.
you wont look like a school mum.
How hard do you drive in the wet? Do you slide it reguarly?

or is it psychological that a 4wd is better in the wet? ABS and good tyres are a lot more important in an emergency than 2 or 4 wheel drive on the road... imho
