Some of these sound like upsides to me. I've owned a lot of older cars, and they're always a mystery box of "what will fail next?". So many moving parts, and they're often hard to diagnose.
Based on your comment, I expect newer cars to have lower maintenance and repair costs, fewer part failures, and less guessing about exactly which part is broken.
