Why are classic 4 door sedans "disliked"?

When I was a teenager I didn't like four door cars. Now I love them. I guess it's something with age. When I got my first truck I wanted a regular cab short bed now I wouldn't buy one unless it was a 4 door. (Unless it's an old truck of course) I'd love to have a 4 door dart or Valiant or something like that now. When I was teenager I would even look twice at them lol. I passed up on my number one dream car when I was 17 because it was a 4 door. A 1964 plymouth fury a running driving 318 with title for 500 bucks. And I didn't buy it because it was a four door. I'd love to have that car now!
