So i went to my dealership- Spirit Corby - today and can confirm that the system is up and running.
My car, a se xr was ordered 19th nov with a request of delivery in march.
The system originally said TBA (great) but using the sales mgrs version it had the car as being assigned a VIN. They would normally expect a clearer status indication, but as the VIN is applied on landing in the UK its apparently at the port. A couple more weeks they said. I suggested online experience stated nearer 3-4 and they didn’t disagree.
