It must've changed hands, because the Ford dealers in San Dog in the late '80s didn't have that name. Do you happen to recall which part of San Dog it was located?
When I said 'San Diego' I was kinda referring to the whole county, which had a number of Ford dealers when I traveled down there for work in the 90's. Did a little research and found out Homer Heller was the Ford dealer is Escondido - I've even been there a couple of times. Dealership is now known as GOScH Ford, which I believe has a couple of other dealerships in Riverside County - like in Hemet.
