thats really not that bad. But if it really annoys you, how about one of those flat magnets.If you attach the sticker to one side, could you just put the other side of the magnet on the trunk or something? Keep it in you glove box and put it on when you get home and then just remove it when you leave. Not sure if it would leave marks tho. I did that in college with my mazda6. it was a red close to imola and worked perfectly.
EDIT:
something like this....
