Mine is the same, I ordered the Mokka 1.2 ultimate auto on the 27th September 2022. When I logged in on Motability recently the application date changed to say the 12th June 2023.
I went on the live chat with motability and they told me the car is showing as ordered on the 27th September and couldn’t explain to me why the date had changed.
As it turns out I still haven’t been given any updates from Vauxhall. I rang them a couple of weeks ago and they said there’s still no build date.
So frustrating, I’ve seen on a Facebook forum that someone else ordered the exact same car as me in October and are picking the car up this week.
No idea how they work these things out.
