I'm in the vintage camp at the moment. I just replaced the Chrysler ignition system that was in my old 80s Volvo for a Bosch one that came in a later model. That and replacing the timing belt took all of one weekend and $500 (I splurged on some new parts that I didn't technically need to). The next week I drove it cross country and had a blast, somehow having the time of my life despite not having the last 35 years of features that many people can't live without.
Toyotas, Hondas and Volvos of that era lasted a long time, and it would have been simple to predict had you bothered to look. Simplicity + Robustness = Longevity. Because of that equation, the domestic long running vehicles are all pickup trucks.
The last era where we had any semblance of simplicity and reliability was probably the 2000s right up to the recession. Those cars and trucks were just the perfected versions of their 90s version. (Except Chrysler, it's best to avoid all era of Chrysler and I say this as former K-Car and Ram owner.)
Post recession we added turbos to everything. Then came CVTs and variable timing and a slew of new engines. And then came the slow and steady computerization and electric motor actuators for everything. The length of wiring harnesses exploded. Why does my car seat now weigh 300 pounds and have 1200 position settings and climate control, etc. etc.
Simplicity + Robustness = Longevity is true for any era.
Jeeps are hilariously bad. Like "far and away statistically the worst" reliability wise.
