The vast majority of ppl treat cars like Styrofoam cups.
After it serves its purpose, they discard it.

It is down to:
- Interest...most ppl don't have an interest in cars.
- Desire to fix...it is a challenge to learn how to fix cars.
- Even if you want to fix cars, parts brands (made in Germany vs China), forum reading, reviews can consume a lot of your time.
- Then very often, the repair is not going well, things break, strip, seize etc.
- Not to mention your significant other complains you spend too much time with the car, while you should spend time on vacation.
- Time: between work, family, and other chores...who has time to mow the lawn or fix cars?
- Budget: dealer is both expensive and mostly incompetent; best is to have a mechanic who moonlights on the weekend but they are difficult to find
Dealers often rip you off. Private shops...are they competent/fair?

If you have a FT job, owning a car and fix it yourself can consume all the time you have left...
But it may be the necessity bc without a functional car, you can't get to work.

So, for young ppl with a FT jobs, find a weekend mechanic.
For old ppl that are retired, you can spend as much as time fixing cars as you want lol...
