it'll cost about $3 to get some Grommits from bunnings or something like that, and it'll take up about 5 minutes of your life
I'm a complete n00b when it comes to doing ANYTHING on cars, computers, or pretty much anything else, and even i managed to do this on my own in about 5 mins haha
Its really easy to do, just open up the boot and unscrew the spoiler, make sure someone is holding it so that when you take the screws out it doesnt fall and scratch your boot
cant really be bothered explaining properly right now coz dinners on the table but if oyu like i can later, but im sure some other good samaratan might
now.. thats doing it with the grommits, which means youll have holes in your boot (filled in by the grommits, obviously), if you want to get the holes fixed, your gonna need your boot resprayed which could be about $300
The only other option you got is to find a VY without a spoiler in the same colour as yours and swap the boots over
so if you do it yourself and you dont mind the little grommits - about $3
fixing and respraying boot - about $300
swapping over for another boot - would be nice in a perfect world, but may be hard to find
