It's more about the materials. Thinner gauges of metal, more plastics, smaller and thinner castings. Almost everything has been cheapened in a modern car. It's not without any benefit though. Lighter cars get better fuel economy for instance. Using the rigidity and strength of stamped steel sheets also allows for both a lighter car that also has built-in crumple zones. Cars are better now but I wouldn't say they're necessarily more durable or reliable unless you're comparing a 2026 to a model A. There was a series of trade-offs as vehicle designs matured. I would say durability and reliability probably peeked in the '90s-early 2000s. Safety and economy continue to get better.

Look up crash tests old vs new and tell me an older car is more rigid or durable

They were and that's a problem. The more rigid designs transferred energy in a crash not throughout the vehicle but towards the occupants.

I'm fine with them being crushed during a crash because that's the car doing it's job. What I don't like is how some stuff just falls apart with time. For instance jeep had an issue with their dashboards at one point that caused the fake letter on top to wrinkle and look like shit. Also they have an issue with radios delaminating and then becoming unusable.

They weren’t rigid due to thicker materials. They were resistant to deformation due to a design that resisted deformation.

We could make cars like that today. But we dont, because it’s unsafe.
