Mark,
I'd very much like to hear whatever you find out as you research this. I may be relocating to the San Diego area (from FL) in the near future and I'd like to have some idea what I'll be up against in that eventuality. My circumstances are different than yours in that my car is currently titled to me here in FL as a '67 replica with no smog equipment (none required) and I would need to retitle it in CA. I have 10K+ miles on the odo, so the 7,500 mile min limit also would not apply. My buddy who lives in Temecula said that I could apply for a one-time exemption, but I'm not sure what kind of rules apply with that.
Please post any info you come up with on this topic, I'll do the same.
Thx,
Mike
