It goes back as it was when somebody opens it twenty minutes or more after it was last put back. Registrations all start with Z, which DVLA never issues, so none of them is a real vehicle. The car photographs are generated, and none of them is anybody’s car. Visits here are counted for Barton’s Bespoke with nothing kept on your device: when, how long, whether on a phone, tablet or computer, and which site sent you. No IP address is kept with them, and they are deleted after six months.
