So after 7 years I finally pay attention and figure out the handwriting on my owner's manual. Turns out it is a horse breeder/stable that originally bought the car. I called and they indeed remembered the car. It was passed down from sibling to sibling and it is quite possible I am only the second owner.

car was originally sold in San Juan Capistrano, CA. It now resides in Western, PA. Quite a trip.
