Newer cars do have lower maintenance and repair costs. This is why vehicles with over 100k miles still fetch a fair amount of money. Computers are very good at doing the same thing over again indefinitely, unlike fully mechanical implementations which tend to drift out of spec slowly over time. A side effect of that is they require more time to actually get in and fix things.

Unlike older cars, the way newer cars work is shielded within software and hardware black boxes and aren't particularly modular. You can't just pull a carburetor out of one car and put it in another. And you're fully dependent on the manufacturer to publish meaningful diagnostic information.
