So then the models are available to dealers as well, which is my point. They have a chart showing which colors are available on which models.
So they know what's coming and what's going
They only have a chart for the models that will be consistent from one year to the next (in this case, where 2022 models will be consistent with 2021 offerings). For new models, the factory sends them a set number in the colors that the factory chooses for the first ordering period. The dealer has little or no say in these units until they place an order after the dealer show.
Yes, they have been given a list of models that are no longer going to be offered well in advance. I don't know them off the top of my head, but I think there are about 3.
