Just was a quick cut and paste from a draft I had, with some editing.
I'm was thinking, based on my case, that a body shop would want you to sign something.
My case was a fight.
That was the reason I cut and pasted some of the items relevant to my car which was completely different than your situation.
My car could conceivably have had mechanical issues or damages while in their possession.
If they want you to sign something, perhaps you might add your own requirements.
That last one is usually in a "contractor's" favor.
It turns that on it's head.
