Any difference in how most cars these days are so bloated? Look at a Nissan Z vs. the original…
I do agree that the US muscle cars in particular could go on a diet. Lots of it I’m sure is safety, but no doubt design is a part of it. Even worse I think is the state of interiors. Most new cars and US cars in particular seem to be seas of flat plastic. Checkout a 60’s Thunderbird or any other of the era by comparison. The dash may kill you in a crash, but was damn s3xy!
