Is that post a joke? I think you're on the wind up now.
You've no idea how long I keep my own vehicles, or works vehicles? So why assume, and build an agenda from it? Strange.
My budget changes (generally upward), and my requirements change, so my choices can change. The fact I can swap my main car after 18 months, with even a far less a hit than I was expecting just proves my calculations correct. My TCO was forecast to be twice as good as a comparable ICE car, and it ended up being even better than that. The car I'm moving to is in even more demand, and I expect that to be even more still when I come to sell it (compared to an equivalent ICE). Effectively I see it as not likely to depreciate as much, as a percentage as my current EV, and certainly a mile better than the ICE I was comparing to, or the ICE I could comparatively get now.
Newer isn't always better, but a 5/10 car from 1980 isn't going to be as good as a 5/10 car from 2000 or 2020. Car engines have got better, as have electric motors, TV's, computers etc, etc. You might have nostalgia for those, but I don't, I'd rather move with the times rather than be stuck in the past.
It's not creative accounting, it's just actual accounting. Maybe you tell your accountant, or boss that he shouldn't bother counting half of their expenditure this year? See how you get on.
Value is subjective, some people would assess what they can get for a particular amount, i.e they might compare two £50 pairs of shoes. You're comparing a £10 pair of shoes with a £50 pair and saying they're the same. They might be to you, to most others they're not. You didn't confirm if you bought £10 shoes, a £1 watch or eat 10p beans, why not? They're just the same as some £50 ones, a £500 watch, or Heinz, right?
Reality is different from you what you believe, and seemingly you have zero experience with.
You talk about advancements, like they are always for the worse, strange mindset. How old is your car, 10 years old? Did you not think that was better than the one made 20 years ago? Do you think you would have anything to buy if people just drove around in old cars?
Cars will always have faults, I've had loads preventing me from moving, from pretty much every manufacturer going, for practically every age of car.
