The GM/AIG type stocks are not the norm, though. And you STILL only "lose" when you go to cash in. Even if the value never returns, you
technically never lost... and who knows, 20 years from now some worthless GM stock you have now may actually be worth something.

But I understand your side, and agree.
I would never borrow money against that. And I pay cash for all my cars.
And yes, the devaluation of a car is certainly a gradual thing, and that is where the self-fulfilling prophecy comes into existance... if you treat it like crap, before too long, it will BE crap.
I own a 1982 Vanagon GL. It sold new for around $12,500. A lot of money in '82. It is in good working order, but what is it really worth now? Maybe $3000 high end? And that is only because there is an enthusiast following for old Buses. But to me, it may as well be priceless because I cannot buy another one, unless I go out and spend a similar amount on one like mine and then not know what I have, or buy one for cheap and recondition it to be like the one I have. The monetary value on it is irrelevent. It is worth to me what it is worth in its usefulness, and nothing more. 7 passenger box that can haul over a ton of cargo, can pull a medium trailer/car dolly, can inhale vast quantities of large lumber and building supplies, camping equipment, wheelchairs, strollers, mulch, dirt, scrap metal, etc. To
me it may as well be worth its weight in silver.
The only issue I see with keeping an older car in good working order and worrying about its perceived value is if you were hit by someone else and insurance or something gets involved. And yes, in that respect the Cobalt (or any GM vehicle really) in 15 years is probably only going to be worth $500 in payout on an insurance claim. This is the only worry I have with my older cars, specifically my Volkswagens, when it comes to value. Otherwise, money is just useless bits of paper.
We are fortunate to nowadays have far superior rust protection than what was once available, even the Japanese cars are better. So longevity in all but the worst of the rustbelt areas really boils down to taking proper care of the mechanicals. Most cars' that have not been severely wrecked end of life cycle is NOT because the car could not be made to go any longer, it is because a human made the choice not to bother with it. Heck, I was just at a local salvage yard grabbing a bit for one of my Toyotas, and the truck I was pulling the part off of was clearly in better cosmetic shape than mine, and it had 100k miles
less on its odometer. Let's face it, we just live in a wasteful society running rampant with gross consumerism.
It's funny, the question of "is it worth it" would probably have a very different answer if so many Americans (and others) were not so addicted to 'buying' things with someone else's money (credit). This Eaglebishi I just got and fixed was had for the price of the tow bill of $60. The guy did not want to spend the ~$1000 or so it needed to be fixed, but he went out and financed $14k on a new Elantra and now has a payment than in only 4 months will have exceeded the price to fix his old car. So which was the wiser decision? And judging by the way he treated his old car, his new car will be in piss-poor shape before it has even been paid off. I just do not understand that mentality, and I think it is probably to blame for a lot of the folks lately getting into the financial pickle they are in.
So I just spent $60 + $800 + some time to fix this old car up, have already put 2000 miles on it, and will likely drive it through the winter and possibly sell it in the Spring.... and it is 100% paid for, which to me is the most valueable car of all.
