lol you literally posted "which one looks better". Three times.
There are no pre-drilled tow hook covers for the RS, likely bc simply taking off the cover and installing a tow hook creates such a negligible difference that it's not worth the time to make a hole in a small piece of plastic, even for those who appreciate the small details (like myself). And if any do exist out there, the owner hasn't posted up here on the forums as far as I'm aware.
But hey, go ahead and be the first to drill yours! Then share it with us so we can all answer the question burning in your mind...which one looks better. Preferably attaching a pic without having to click on a random link, thanks.
