Each dealer gets an annual allocation. It's roughly based on previous sales performance, so varies by dealer. It's possible in more normal times to shop around and find some dealers have fully sold their allocation while others still have spots left.
For the Emira, all dealers have sold their 2022 allocation (delivery now delayed into early 2023). Beyond that they are all keeping lists of deposit holders but don't know what their allocations will be for 2023 or 2024. Some have a rough idea and some are guessing.
Usually allocations for 2023 would be sorted in Q4 2022, but with the rollover of 2022 allocations into early/mid 2023 deliveries, I suspect new allocations may only be confirmed early in 2023. Lotus will also hold back some allocation for planned new dealerships.
Deliveries are usually in monthly blocks, so dealer A has (for example) 48 cars allocated and gets 4 cars each month, while dealer B might have 24 cars and get 2 delivered each month.
