My story is rather uninteresting, but let me know yours. Does this idea also apply to you? You could have the money to buy a new car to replace your old and broken one but you prefer not to touch it. Do you hold yourself from spending what you have to the point of depriving yourself of what you deserve? Do you keep significant savings for occasions that might only happen in your imagination? Or at what point would you allow yourself to be drained of your last penny?
I never heard a story before where people died of thirst in the desert carrying full water bottles with them. Wouldn't you eventually start drinking it before you die? I can understand that you would not drink all your water at once, but wouldn't you ration it at least so you survive the longest. Another point is that due to the heat isn't the water going to vaporise eventually so, you should better drink it before? And I remember reading that people stranded on sea would drink their own urine to survive longer, for that you would need to drink the water sooner. When it comes to life and death situation there is no point in trying to save for bad times, it's all about survival. In my opinion saving money is an important part of everyday's life. We don't know what is going to happen in the future, there could always be a big disaster like the earthquake in Turkey and Syria. Without any really savings we could be in deep trouble. Also don't we want to leave some money behind for our children? We all got money from our parents and grandparents, shouldn't we do the same and leave some of the money we have for the next generations? That is why I would never drain all my money without thinking about the rest of my family.
Well the example about buying a new car because someone deserves it is very different from refusing to drink water risking to die. I do indeed know a couple of very healthy people who always drink sufficient amounts of water, but they are driving a crappy car because they prefer to bunker their money.
One thing you mention is true: hiding money under your pillow in times of inflation isn't the smartest thing you can do, but spending your money on stuff that leaves you without cash in an emergency is probably even dumber. Depending on the usage of a car, I assume that a dollar is devaluing slower over time than a car that is used frequently (unless it is a fancy old timer or whatever, you know what I mean).
I guess everyone of us knows somebody who could afford a lot more things than they actually do. My grandparents were the best example for that I guess. They drove a car that was 20 years old or so and they always had the money to buy another one, but they didn't. Yet they had been living a healthy life with healthy food and lots of water.
Now one argument against keeping an old car could be for security reasons. You are probably safer in a new car than in a 20 year old car.
