That does look well, I like the way you didn't mimic the 180sx style (everything from the underside of the windows upwards) because the line on the side of the 15 wouldn't suit it
thanks for the comments guys... pretty happy with how its looking now. always wanted to have a black roof, s15s as you know don't have the middle panel which made it a tad difficult. its only vinyl so not permanent, i wish it were glossier though
