1. I dont see any link with Grumpy from the seven dwarfs :?:
2. I would'nt dream of using a sticker with any sort of swearing or similar words on it.
So for me, the sticker makes no sense at all, bears no relation at all to old vw's and in fact will say something negative about the owner of the car it is attached too.
But aside from that, Hello sunny Tauranga! I am SO jealous of your weather today! :d
