I don’t really know. It was before my time, I was born in ‘68, but I have seen the old commercials for it. Maybe the advertising was really good compared to others, and there is a feeling of nostalgia and pride that goes with owning that car? Also, I think the fins were a big deal, someone else said that above. There were raffle contests that were advertised for this car also.
I’d be curious to know how much advertising was don’t for other cars at the time and also this might have been when more and more families were starting to own cars. The move to the suburbs was in full swing at this point, and cars were necessary, and even teenagers were buying them. Maybe it is a coming of age baby boom car? It is when the first boomers would have been turning 16. I’m just guessing on everything here, I really don’t know the answer, just offering ideas. I could ask my parents, but they didn’t drive until their 20’s so I don’t know if they would know.
