• the body parts are cut relative to each other according to aesthetic and technical criteria which are generally always the same. Thanks to this almost universal cutting, we can talk about bumper skin, front fenders, rear fenders, and so on.
• the cutouts are not exactly the same, the body parts can be more or less extended.
