I got a Private Offer certificate when I purchased my 2023 Bronco in mid-January. I originally ordered it in November, 2021, then reordered it in September, 2022. It got scheduled and built by December 9, 2022 and delivered to my dealer on January 13, 2023. The certificate was hard to track down, but it finally became available about a day before I was scheduled to pick up my Bronco. It saved me $2,450 as I recall. It used to be regarded as "price protection," but that term fell out of favor with Ford and/or the dealer network.
All that said, I'm not sure if my certificate is what you're referring to. I don't know what you mean by "Bronco Order Modification Private Offer." Is that the same thing or a completely different thing?
Chris here. I drive a 2-door Velocity Blue 2023 Ford Bronco Badlands with Sasquatch, Lux, a 2.7L V6, and an automatic transmission. It’s fun.
