I would go for inside the window....but the removal static cling kind.
What would views be for a similar print on spare tyre covers for 4 x 4's. I guess these would work out expensive but if you have demand !. It would be visible from quite a distance. Just a thought.
He he, I've had a few people ask about a car sticker, how many people would really be interested?? I'll look into it
Thought number 1 - Great Idea!
Thought number 2 - "This car is probably transporting illegal sharps Sticker". Am I just paranoid?
