Hi,
Ouch, must have meant a change of pants !!!!.
If it were me, I would take a lot of photos and keep a copy of the parts replaced. Any competent garage will know it's been in an accident if you come to part exchange it and will want to know how bad it was. If you have got the evidence to show it wasn't bad, it won't affect the value.
My wife reversed our new Ulysse into a wall and caused £1,500 of damage. The first repair wasn't good as they cut corners so I made them do it again and now you would never know, so give it a good inspection when you get it back.
Good Luck.
Andy
