What made A bodies non-popular

I know a lot of people that think A Bodies are ugly. Back when I bought my first Dart, it was because no one wanted them, and you could get them for free, or close.

Compare numbers with the Mustang. They sold over a MILLION mustangs in the first two years. When I was in high school, I couldn't afford a Mustang. Now, they are easier and cheaper than a Dart. Bastards. The main reason is that there were so many more made, they are less rare.
