That’s not a reservation.
That’s an agreement where your dealer was offering something they don’t have.
ETA: I reserved on 7/13/2020, fought through the crashes of the Ford website, fully thinking that I needed to get in early for my chance at the best Bronco that I had already been anticipating for at least four years, following all the renderings and iterations of new forums to discuss it. So, I love that Ford is rewarding our genuine enthusiasm instead of putting this on the market to the highest bidder. That’s just me, though.
