On the actual flip side, there are plenty of people who properly maintain vintage sports cars instead of just talking about how much they know about them.
I get that door handles and lock cylinders are often made of easily-broken pot metal, but most owner communities have figured out solutions, or just live a little and recognize that a locksmith can easily get you into almost any vintage car if necessary.
The starting problems mean your engine is poorly tuned/maintained, battery issues are bad wiring or undiagnosed parasitic drain (or just buy a battery maintainer, dude), and thinking "my first gear syncro is worn or my shift linkage isn't properly adjusted, I should mash the shit out of it" are purely owner error / strongly counter-indicate "I know a ton about cars."
