Waiting list orders in germany are basically binding purchase offers you sign with your dealer. You do everything, the paperwork and the financial parts and the paperwork will land in the dealers desk drawer. Maybe they can enter it in their local system, but these orders are NOT entered on the German/Europe Toyota order system, because that one is closed.
Being an binding purchase offer, you basically only have fixed order conditions the dealer has to follow IF he can allocate you a car. It does not mean that you get the car at all:
When the systems open again, all local dealers need to enter the purchase offers into the production system asap. With that being said, I assume there are already waaaayyyy more parked orders than available cars in the 2nd batch (rumored 500-600 again). So it will be a run for the dealers - and many people that wait will be disappointed.
My dealer told me he will process all waiting list orders in chronological order by order date, when the system is open again.
