Went and had a look and it's a wonky, 50 centimeter long scratch that's down to the metal.
Royally peeved, more because of the fact that it was targeted at me as the other 10 cars on the street didn't get scratched. I haven't wronged anyone at all or remember cutting anyone off or anything. Likely a key or knife was used.
I've asked the business that was over the road to check to see if their security camera for their carpark reaches the road and they said they'd get back to me... I hope it's a good result or else I have no other way of finding who did it, for all I know it could've just been some jerk that was jealous of my GReddy SE

Sorry, was just venting my frustration a little. Just a really crap end to my otherwise decent day at work.
Hope it's not too expensive to fix
