I have an SVTF with the SVT side skirts, and personally I've been wanting something like this since I got my Focus. I really don't like the "plain" look of the SVT skirts, but I love the idea of wrapping the same black trim that's on the front bumper down the sides. It's much more attractive in my opinion to continue that trim all the way around the car, not just stop it at the front wheels. This look would be a much better option than most of the garbage ricer-looking aftermarket body kits that are out there now.
I agree with most though, If it has the same color and texture as the current black trim, I'm all over this kit (and relax, I know the photos are just a prototype and a working model. But it definitely gets the idea across).
