It is possible that Ford might deploy the B&P to their site now and set it behind a toggle/flag so they can do testing in the production environment for the next few days/week. Not super common to test in prod like that but maybe. It's more common if they had a pilot user group that they'd toggle the B&P on for and they'd be real world testers. Maybe they're doing that for the dev team and/or other relative internal employees.
If you go on the build and price tool from the main page it doesn't show up. But if you go onto the bronco page and then to the "explore this model" page, scroll to the build and price at the bottom and the bronco shows up
