On further inspection this morning I've noticed some gouging to the Nissan badge on the boot. You can see it on the 5th photo I posted, I'm guessing that they used a long screwdriver to lever up the OEM spoiler, resting it on the badge as just above the badge is the deepest scratch of them all. Looking at the old spoiler, you can clearly see in several places damage to the bonding caused by a screwdriver or something similar. I'm still weighing up my options, problem is I'm a non confrontational sort of person and on top of that there are other, shall we say complications, that I don't really want to go into at this stage. I have phoned them up and spoken to them but they replied that the damage was already there when they removed the OEM spoiler, so basically they are denying responsibility. Not really much I can do, getting into abusive arguments isn't in my nature and I'm pretty certain that's what it'll come down to. Caroline is absolutely furious, she knows how well I've looked after this car since I bought it in 2007 and once again, for reasons I won't go into this could make things complicated. Unfortunately, this experience has really put me off any further modding, for now at least .
Thanks for all your messages of support BTW, I appreciate it.
