^ I don't think I'd ever wear used clothes - they're cheap enough when new.
That really depends where you live and what kind of cloths we're talking about.
Being raised in ex Eastern Bloc, almost all of my cloths until I was 10 or so were used. It was pretty normal to buy used - especially for growing children.
I would be surprised if this wasn't still the case in less wealthy countries - even with endless supply of awful but cheap cloths from China.
But moving to wealthy countries, this is actually coming back as part of a "zero waste" idea, which I'm actually quite fond of.
If a piece of clothing can survive long 60*C washing cycle, it's probably cleaner than when it left the store.
Spending $30k+ for a used car is insane to me... if I want to spend that much, it better not be used with a further-limited shelf life and questionable treatment history... I'd rather finance the rest as new and take my time paying it. Something used in the $5k range as a beater/daily though, sure. My kids will be getting that because it makes sense.
Well again, it's a matter of wealth. In many countries just a tiny fraction of people can afford something new.
Cars - being expensive - are designed to last and to change hands once in a while. That's why their history is being tracked, usually by the gov.
I've only bought a single car in my life and it was a new Toyota Aygo, just a few years back.
My girlfriend really wanted a car and we went for a new one for a single, very simple reason: I really have no interest in cars, I didn't want to waste money and time on checking and fixing. I wanted something robust with warranty.
But for people who like cars OR can afford taking care of one OR have higher expectations than I do (about speed, features or interior quality), buying a 3-4 year old car - ideally one that was leased - is by far the best option.
Furniture I don't always agree with either... bed bugs, etc.
Bed bugs live in mattresses. You should replace them every few years anyway.
I was thinking more about tables and wardrobes.
PC's, only if it's a backup not used daily will I go for something dated. Need the power if it's a PC as opposed to throw-around tablets and smartphones.
I find this fairly hard to agree with. The PC you owned 5 years ago would be unusable today? I mean: for daily casual use, not for gaming or comparing benchmark results.
People tend to overestimate the importance of PC performance.
I'm currently looking at 2 PCs: my personal desktop and a work laptop.
I played Forza 4 for 2h last week, I edited some small 4K video yesterday.
Apart from that, everything I've done on either of them, both personally and for work, could have been done on ANY of the PCs I've owned since 2010 - running the same software (including W10). And I buy pretty basic stuff normally, you'd call it "office grade".
