@Rolly, what a downer. But easily fixable.
It’s brilliant you’ve got pics there for back up.
I’d call Motability for advice but would definitely call the dealer and explain. As the car is new and was damaged at the dealer and before delivery, Motability may want the dealer to take ownership.
This is what Motability say about minor damage but your situation is slightly different.
Either way. Good luck. ?
? I will be remembered for nothing but had great fun doing it ?
