Kikoba, for all means if you want a backpack on wheels the forester would be it. That was the main reason I got the forester over the impreza. There is a lot more room overall inside the forester than the impreza. There is definitely more "utility" in the forester. I have taken my ride up to the mountains for skiing and through the Olympic forester park up here in WA state and the forester handled every terrain wonderfully. I love the WRX but I wouldn't be too comfortable in it on long trips.
Well, its all based on preference so have fun!
