First glad that you are ok! Good luck on locating a good body shop.
I have been into the same situation.. sharing the estimates (all OEM parts)..
The difference is the other driver insurance covered all the liability.
Note: Watch out for the estimates with LKQ Grade A - most of the time it is damaged. I'm glad the adjuster approved all BMW OEM.
