I wonder if you have changed anything since you ordered, not necessary anything to do with car but maybe adaptions ?
I say this as my order date changed when I decided I never wanted the hoist I ordered with my car. I ordered the car and hoist in October 2021 and told the dealer and Motability that I did not want the hoist as I made other arrangements.
My order date changed to the day I changed the order sometime in April 2022 but this had no effect on the delivery time of the car as they were unrelated.
