Just be carefull.
Your agreement puts a duty on you to notify motability of accidents and damage etc
You also have a duty to report accidents to their insurers also.
I’m sure motability would see failing to notify them as worse than recording the accident with them.
Be sure of what you do as being underhand may risk your lease.
If your friend has no insurance to cover the liability then RSA may not pursue them for the cost.
I would be in a dilemma if it happened to me as I’m a named driver on another policy which would be affected by recording an accident.
Don’t forget when taking out insurance either with RSA for motability or any other car they ask you “have you had any claims or accidents”. Your meant to declare accidents you claim for and accidents you dont claim for and if they find out you lied or withheld information you can have your insurance nulled.
My point is that if your going to get it repaired yourself make sure its done properly. If it comes out at a later date you’ve not declared a fix you may shoot yourself in the foot.
I’m experienced in accident damaged vehicles and repairs. The only way to fix that properly is a replacement door. But even if you buy the same colour there is a remote chance of noticable shade difference in the panels which may need further work.
Depends on comparable age of the panels and comparable wear to the paint surface etc.
It may not be a simple case of swapping the door.
