I’d suggest getting the order number checked & then going onto bmw live chat & asking them there. They seem to have no customer service filter they just tell you the dates.
my dealership has taken a deposit on ordering. according to genius the dealer ordered out of capacity which cancelled it and pushed it back. Then it’s been capacity checked repeatedly and pushed back to February from a March order.
I’d also keep an eye on the advanced payment. If delivery was in quarter 2 as on my paperwork mine would’ve been £100 cheaper than today’s price.
looking today – my alternative vehicle orders q3 or gla are no longer even on the list
