Pretty cool. I wouldn't ever cut up an OEM hard top but this would be awesome on an aftermarket hardtop. The one thing I never liked about the original lightweight Mazdaspeed hardtop, besides the insane cost and limited availability, was the rectangular shaped rear window. This TRAP item gives you the best of both worlds.
