Just spoke to a SA. My current expected delivery slot is 15-29/3/22. No VIN yet but told I should expect a text next week with a EDD as I'm not matched to a specific car yet and that my M3LR is on a boat but he couldn't say which one
, however more interesting, I mentioned that I can't miss a March delivery as I'm on holiday most of April and he said that "they will not be delivering any UK cars after 31/3/22 and that they would be moving all heaven and earth to complete March notifications as next deliveries would be May time.
