Mine didn't have anywhere near as much damage as yours.
I was doing about 15 - 20 mph when a woman came off the pavement into the side of me (just off a roundabout).
There was a dent in the front side wing, that joined to a dent on the front side door. There were scratches down the back door and rear side too.
Took about 3 weeks to get the car agreed for repair, then took about a week to get it repaired.
It looks good as new now, it's had some spraying for sure - though I'm not sure how much.
On top of that they repaired (or replaced) my alloys, even though the scratches was curbing (I said the other car caused it hahaha)

.
They also Valeted it inside and out , and it smells and looks good as new.
I've just taken down my r-plates there when I got it back (on saturday) and It's great to have it back - I'm still a bit more nervous on the roads even though it wasn't my fault.
The claim is going to be tricky though.
