Interesting link - looks like it could be quite a resource to the criminal minded...
I've not seen too many real swedish plates, but I would imagine this one is pretty accurate. The white paint is that reflective stuff that US plates have and there are also watermarks that you can only see at an angle.
The only thing that I wasn't sure of was if Swedish plates had the euroband on the left side. But, I think a couple posts back you said they did. If anyone wants a custom plate, I would highly recommend licenseplates.tv. I am extremely pleased with the quality of my plate.
