Thanks for checking. I'm in Michigan but I'm always up for a trip to CA!
I have spoken with the last 3 owners which takes me back to around 2006, for which this owner recalled he was the third owner, and he bought it from a gentlemen in Chicago who had it for around 10 years before that.
Sometimes it is best not to dig up a car's history, but I do like understanding the history and understanding what was done to the car (repairs, internal engine mods, etc).
I am still waiting for a confirmation email from the registry - took numerous attempts to get that far and I think it has now been several weeks waiting for the email.
Not a huge deal as I think I have reached the end of the history trail.
