There are a few school of thoughts involved.
Those buy new underwear and buy more after the season is over and those who patch and sew it up and continue to wear it till there is a hole for your pecker head to sneak out to see some sunlight.
Like my aunt sally once told me, how is the economy gonna thrive if you are not a continuous buyer?
So the rich is playing the leasing game. You always see them driving new vehicles after a few years and you think they are well off just because they are riding new rides all the time. They don't even have to worry about the maintenance cost either. Only the poor guy is shelling out for maintenance care because he wants to keep his vehicles forever and ever.
Then there are mediocre guy like myself. I buy new, drive for 10 years while abusing the vehicle and sell it at 100k mileage for easier to sell. The next guy will have to hold my bag cuz parts will die after a while. You want to know when your parts is gonna die? Just look at your warranty. They are smart enough to give you a warranty just about the time that they think your car is about to die.
I like to fix cars myself and to me, I want to make memories for myself. I want to see how far can I get a car to go before I retire her. Only gripe is you just don't know when you'll be stuck out there on the highway. Worst feeling ever. $700 to tow from the bay to my garage was what the tow guy once quoted me.
