First off I am so sorry that happened to your BRZ. I would be sick to my stomach. The only place that I would go is the same place that all of the GT-R owners go, Seidner's Collision Center. I have never heard a bad review from them.
The one in Fontana is amazing and has done amazing things for forum/local members. They also have fair pricing. If you call talk to Brad Cermak he is the Manager.
Feel free to PM me if you have any further questions.
