It's nostalgia, plain & simple. I understand it too. But don't conflate nostalgia with "everything's going to shit". That's what got us MAGA.
I had a 1965 Chevrolet Impala when I was in high school and college. I loved that car. I experienced some great things in that car. Great memories. I have a nostalgic love for that car. In the late 80's, I fell into some money, so I decided I would get my 1965 Chevy Impala convertible that I always wanted. It showed up on a flatbead and I gleefully jumped into the driver's seat and started it up. Ahh, there was that sound of the 283 V8. Man, did that bring back memories! I was in heaven.
Then I drove it.
What a dog!! You could move the steering wheel back & forth for several inches and the car would still go straight. You turn and the whole front end nose-dives into the corner. No road feel. You float along. Hit a bump and almost bite you tongue. Put the top down and forget to unzip the glass rear window and it shatters. Snapping on the tonneau cover was a joke. Most of the snaps wouldn't snap and every other one ripped out of the vinyl. And then run out to the car in the sun with the top down and jump in with shorts onto that black vinyl bench seat. Mother %$##$!!!! The worst was those frickin' bias ply tires! You go into a corner on an exit ramp and hit a bump and the car walks off the road. Scared the crap out of me. Radials went on within days.
Worst car i ever bought.
