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.

Haha, funny indeed. I live in San Juan Capistrano right next to the horse stables. What is the owners name? I probably know em.

Didn't get the actual name of the owners. But I talked to a gentleman there.

Sycamore Trail Stables.

Funny, I used to date a girl that had a horse kept in those stables. Big huge black stallion. Knocked over one of the owner ladies that was riding on a golf cart, broke her leg I think. Could be the same person!
