>Once a car gets older, there's usually no shortage of the electrical components on the secondary market as they're getting scrapped

Usually the lifespan limiting component is the same on all vehicles of a type so there's a shortage of exactly the part you need which makes it economically nonviable.

>figures out "Capacitor 96 goes bad on Part 420" and solders a new one in.

Car PCB's are often conformally coated or require destructive disassembly.

>We'll run into problems once they "marry" all the electric parts

Already happened.

Varies across a country/continent. I'm in the salt belt so it's the body/suspension that gives first while it's whatever heat-deaths first in the US south.

And we have bad drivers in north america which helps the market for non-front/rear body components.
