While it is true that much has changed in car design in the name of safety and efficiency, it has been recognised that so many new cars are bland and just plain ugly .You're right that car shape has aligned over the decades. There's loads of reasons but I doubt we'll ever see an era where new cars come out looking like a Ponton or grosser or Chevrolet bel air... They're just not efficient or safe design choices.
As said above, I certainly pay attention to fresh metal, especially if it's expensive, as I've aspirations of owning it one day.
This car above, I'm sure I saw the very same the day before. I definitely saw the same model, and the plate looks too familiar too. It definitely drew attention, not just from me.
You just have to look at the many car makers who now take styling cues from earlier models :
Mercedes restyled the front end of the SLK to have a classic grille reminiscent of the W121 190SL
Then there was the SLS/SLR , complete with gullwing doors as a nod to their 1950’s counterparts
Current model VW Beetle , perhaps a dressed up Golf but it stands out from the hatchback crowd
Fiat 500
Jaguar S Type perhaps a Mondeo under the skin but styled to look like the Mk II
N doubt many others
