For the cars, I think it depends, possibly even on your luck. My car is old enough to vote, and aside from one simple repair I could do in 15 minutes in my parents' garage with a part that was sold by the dealership for 60 €, it only ever needed changes of consumables. Hell, even the scheduled maintenance at the stealership costs a song, cheaper than my motorcycle.
My dad's cars from the same era didn't fare so well and all required heavier repairs; none still work.
Also, since we're talking anecdotes, my parents have thrown out all their CRT TVs and monitors because they've all failed in some way (I've personally never had any). And I'm typing this on a Dell LCD monitor from 2015 or so that still kicks ass and has great picture, even by today's standards. My 2013 MBP still has a working, good-looking screen, and it's been on the road a lot.
> Forget that, is there anything you've bought new in the last _ten_ years that you still have?
Yup, almost everything [0] still works like new, even my 2013 MBP which I've carted around a lot. It's not powerful enough anymore, so I have a new daily driver, but it still works. Hell, my gaming PC was bought circa 2013, and only had a new GPU 3 years ago (was bought for server work initially, so only had the cheapest GPU I could find). Still rocking the original SSDs, PSU, everything. Ditto for my wireless headphones I bought around 2018. The battery life is still good, the sound hasn't changed.
I've mostly lived in rental apartments, so I don't have any anecdotes about household appliances.
So not really sure what can be concluded from our anecdotes.
