Can't you just show that it's fully booked without a car? It takes 2-3 days to go back and forth ?

Adjust the pickup and drop-off time within the application time and try it.

I cancelled once, and later learned that I needed to select "immediate confirmation" in the "filter" to be able to place an order for the available car models. Otherwise, all orders need to be confirmed by the dealership. You can try it out. Unfortunately, there are too few remaining car models, and now I don't know what to do.
