Welcome to Ferrari Life. I would try Sal Garcia at Waterfront Automobili, his number is:
(415) 861-2223
For a body shop I am unsure (never had a ding, knock on wood). Be sure to tell Sal that Andrew Naber from Ferrari Life sent you. He does all my work on a 308 GTS QV and F355. He also owns a 308 himself so you will be in good hands with your 308.
