Use the link on the page and the respective passcode shown to sign up. There doesn’t appear to be any verification though, unless I have missed something.
I don’t drive myself so can’t really comment on how useful the status would be. But from what I understand Preferred is a free scheme which anyone can sign up to. President’s Club seems to be the sweet spot as you can expect a single or double upgrade at least.
