I really do sympathise with you mate. Over the last 3 weeks, I've had mine keyed a few times:
1. Along rear driver's side door
2. Boot to bonnet driver's side
3. Boot to bonnet passenger's side
Bit overcast today and the colour of the car doesn't
help, but here are a few pics:
And I had some sort of cleaning chemical poured on the windscreen and driver's side front wing/bonnet. Strangely, this chemical did no visible damage. "So how do you know it was done then, Rich?", you may ask. There was a strong white spirit smell in the cabin after starting in the morning. Didn't twig that anything was wrong until I got home from work and the smell was still strong. Smelled all around the front of the car and it was unmistakable. Looked on the floor where my car was parked as well and there was a drying puddle of the same-smell liquid on the floor.
Anyway, I'm not going to even attempt to get mine fixed until I get CCTV fitted because they will just don't again. I have my suspicions of who it might be and they wouldn't think twice about performing this cowardly act again as soon as it was fixed.
