Why the hatch? Well, my last car was a 91 Honda Accord wagon with 200,000 miles on it. I got used to the conveince of a wagon. I was actually shopping for a used Outback XT 5 speed, they are rare. I know I made the right decision when I threw four snows mounted on steel wheels in the back so I could swap them over at work. Sure I could have done this with the sedan, but it was so much easier with the hatch. I tested the back as a possible sleeping spot. I think I could do it kitty corner. I'm 5'11".
I'm a skier and a mountain biker, so this was also a consideration. The looks of the hatch have grown on me. As someone else on the forum stated, it does resemble a baseball cap. I guess all hatches do. I think the sedan is probably quieter, I do notice debrise hitting the wheel wells in the back. This is less noticable in the sedan I'm sure.
I think you'll be happy either way, these are great little cars.
