As a comparator, my order was placed 9 Oct and accepted on the system 14 Oct; now #38 on the list, having previously been #96. So doesn‘t seem entirely chronological.
If it helps with your conversation, I grilled the dealer on what components were causing delays - I didn’t want to delete the towbar just to find out that xxxx was also a known issue thus countering any benefit. They said that there were 3 specific options highlighted causing extended delays, removal of which would bring forward build dates; towbar (specifically electrics), tyre pressure monitoring system and the sports/style packages. I’m only affected by the towbar but know you have at least the sports pack specified.
