That's all I would be concerned with. I know some stickers are a pure pain-in-the-ass to remove off of a painted surface. And the advertisement of what's under the hood and in the car would unsettle me a little - not at home, but if I ever drove it out somewhere and couldn't keep an eye on the car. You know?
Anyway, the Mustang kind of looks like a sleeper with that 617hp but I'm guessing the Vortech whine kind of gives it away
