I'm new, but the car is old.

beautiful car !!

As for the black in the engine bay, a bet a little bit of thinner would take the black paint off.
And any good (and I don't mean national chain or cheapo) body shop can fix the rust and blend the paint.

Looks like it was a radio delete car.

Next time you go to a car show..look around for really nice cars and ask the owners who did their paintwork.
