The thing that sets this spoiler apart from others is that it bonds to the glass of the rear screen, so does not require any drilling of the hatch, and is quickly and easily removable and reusable.
Mine has never been on a car and still has all the fitting kit with it, I've even got the original product code somewhere? All I've done with mine is spray it black, never got around during to putting it on a car yet as the one it was intended for unfortunately got written off.
The first two pictures below are of my actual spoiler as it is now, the rest are for demonstration purposes to illustrate what it looks like on a car. The car is that of the guy I bought it off, Lee.
Any info appreciated. May actually sell this as currently have a spoiler on my GX and can't see me buying another micra as I have a classic now too.
