I'd start by using typical sites that have them listed and get on the phone. That's really the only way you are going to get anywhere. Have you called around yet?
That is going to be a tough nut to crack in CA. I just talked to a local dealer that has a TO car going to the body shop this week and he want $10K ADM, and this is a small family owned dealership in a very small town. I can send you a PM with his info if you want to see what kind of a deal you can swing.
