As long as the vehicle is reasonably dependable. Sometimes an older undependable vehicle might not be worth it. (think of stranding a loved one, or dying in winter, etc)
That said, brand new cars without spares are a disturbing trend.
I knew a retired guy years ago whose speciality was fixing microwaves; any dead microwave you could find he'd get working again. They still exist, but they're nearly impossible to find unless you hear about it.
I know I'd love to find someone to offload these old SpeedQueens on (even there, a burnt out motor was $350 to replace, a brand new one was $700 or so).
I had a friend who (years ago) bought a version 1 humvee, but it turned out to be impractical, struggling to achieve highway speeds while guzzling gas like a toilet.
Almost any modern refrigerator is quite reliable and energy efficient compared to ancient ones - but wash machines seem to be retrogressing in quality (and only partially can the blame be laid on the energy/water saving requirements).
A $30k car? You'll pay a mechanic to fix that, it's too valuable an asset to just throw away (and even then, you see people selling cars with "something broken" that is not economical _for them_ to fix, but if you know how to fix it you can get a car cheap).
A $500-1k wash machine? Unlikely to be worth the $100-200 to bring out a repairman (because now you're looking at a $200 "discount" on a new one, which is probably much more "advanced" (if that's good) than the existing), so it gets tossed.
