Sorry to hear that you got bumped
Hope the damage is not too bad.
I think if you shop around, you might see that price ranges are huge. I have some rocker panel damage, and a chain, like "California Caliber Collision" quoted me just under a 1k to fix. Then some nicer body shops that claimed to specialize in nicer cars quoted me 1500-1700. Then some more ghetto type shops quoted me 700 cash to fix it.
I still haven't picked a place.
I don't have any recommendations for west LA, but wanted to share my experience so far.
You local Porsche dealership should have a shop or 2 that they recommend - that might be a good place to start.
Good Luck,
