That's interesting that it was sold at Rector Cadillac in Burlingame. I have bought a few cars at Rector over the last 25+ years and it is about 5 min from my house.
If you get the original owners real name let me know and I can try and find him. Rector is basically in the same families ownership but went to husband of the original owners daughter.
You can try calling Randy Hill in the sales department at Rector. Long shot they have any records but you never know.Randy is a car guy and has raced open wheel cars for years in SCCA . You can tell him that I (Van) told you to call.

Nice looking car.
