The more I look at it I think its a cross between the Impreza and Matrix.
Completely. I bet the average person would have a hard time telling the 3 apart.
I think it looks decent, shame about the face. I also find the rear bumper to be over-styled. It's as though they were trying too hard and failed to come up with a cohesive design.
It is me, or the hatch space seem small? In my P5, the hatch area is cut-out around the wheel wells so there is a spot at the rear of the hatch space where my golf clubs can fit perfectly (I swear they planned it). It's useful to have as you can put longer items across the back or stuff extra things in the space. With the hatch space being perfectly square(ish) I bet golf clubs would have to be placed on the diagonal, taking up much more space.
I still think from a styling perspective P5 > 1st Gen 3 > 2nd Gen 3.
