Not worth challenging the dealer more than asking for free mats IMO.
All colours were including in the AP. I think they should have really lowered the AP and had the colours priced as you’re right. But like us who ordered the jungle green, the colour it’s changed to is a generic much cheaper colour.
I’d double check with motability about the cancelled order though. They mentioned that the systems have changed and when you order a car you can’t source cancelled orders anymore? Unless the other order was motability too
