Sorry to hear about the accident and welcome to the CC. I have used Mathew-Carlsen Body works in Palo Alto, Mathews-Carlsen Body Works.
Someone backed into my Cayenne S and these guys were recommended by several people. When I went there they were first class and reasonable, doesn't sound right, but true. I never saw so many Porsches outside of a dealer's lot than at their shop. The workmanship and service was excellent!
