I don't like advertisement as well. Luckily the dealership I worked for told us to leave Front plates alone until vehicle is Sold, because some out of state buyers doesnt want it.
And we do not use dealer sticker or emblem. I think it is ugly
plate frame is as far as we go.

 

It's just advertising. Every year I'm part of a 6 day, 350 mile fund raiser bicycle tour. We are always looking for sponsors. I always tell 'em I'll wear a pink tutu with their logo if they donate enough $$$. LOL
