A PCO is a Private Cash Offer given by Ford directly to a customer, kind of like a coupon. They are usually received via mail or email to potential customers. I will tell you there is no 100% way of getting one.
Some of the ways of improving your odds of receiving a PCO are calling or emailing Ford and asking to be put on the PCO List, opening a ford.com account, building and saving a vehicle on the Ford website, requesting a vehicle brochure from the Ford website, utilizing the FordPass App, look for Ford offers that pop up occasionally on other websites. Wish you luck in your search.
Below is what one of mine looked like. They do exist.
