Most people don't really care about cars. It's a tool that gets you places and carries your stuff. Ideally for the lowest cost. People care a lot more about safety ratings, fuel efficiency, and resale value than they to about unconventional design.
I think it was the same in the 50s and 60s, just that the then car manufacturers hadn’t figured out how to compete in the other more important aspects as effectively.
Proof: look at a 1970 'Cuda. Tell me you wouldn't buy it in an instant if you had the cash!

Have fun with your jellybean! (Sorry)
In any case, the '67 and '68 Mustangs are the best looking of the Mustang line, and the '68 Dodge Charger is to die for.
If you cannot tell the difference, may I suggest you spend a wonderful evening watching "Bullitt".
When I was in high school, a friend of mine bought a '67 Mustang for $200, so of course he offered me a ride. I had never ridden in one before. I barely had the door closed when he stomped on the gas. What can I say, it was a transformative experience! I soon acquired one for myself. Converted it to a 4-speed, hopped up the engine, and had a grand time with it for years until a garbage truck turned it into an accordion.
I still miss that car.
But I did wind up replacing it with a 72 Dodge Challenger, which is close to being a Cuda. I spent a lot of money on its engine in the machine shop. I enjoy every second driving it, and giving friends rides in it.
Like me before I got the ride in the Mustang, you gotta get a ride in one before you dis it.
I'd still rather have my 20-year-old 350Z.
It has heated seats, heated steering wheel, AC, backing camera/sensors, uses electricity which means it costs practically nothing to drive, doesn't make noise, isn't hard to get going in an uphill, and probably about 100 other advantages.
