Yes, you can surely pre-order a 2020 Ford Bronco. But it will not be available for preorder until towards the end of the year. However, the vehicle would start to be produced and delivered during the early part of the year 2021. As a matter of fact, the time for the delivery of your Ford Bronco can be quite different, depending on some factors.
The factors include your location, the model, and configuration of your vehicle, and also, as your demand might be. No need to worry much about this though, you would be sent a further notification immediately after your vehicle has been scheduled.
In addition, you are not making you preorder directly from ford; you are only making it from a dealer. Nevertheless, you can make up to two reservations on one account. You will have your reservation number assigned to you, and which cannot be transferred.
