Or how about an easy addition to the site sticker?? I say easy because I have no idea how hard it is to reformat a file and have it made. My attached pic is clearly terrible but you get the idea.

What do dealerships use to write on windows? Some have a pretty fine tip that would work for the space provided... Aquarium stores also have pens that write well on glass but I don't know how these pens hold up to the elements. I don't really want to have to re-write on my window every time it rains... (even though I'd be re-writing every time my avg mpg changes lol)

But if there is a good pen it could be sold as a kit with the sticker. Yellow would work well whether or not the glass is tinted...and stand out to draw attention.
