Yep. That's a beautiful car.
Maintenance ...no more or less than any other car.
I'm sure all the parts are still available. - The car is not 'that' old. - In comparison to me anyway. lol
It can be a fun car but Old cars do require more maintenance than the new ones.
in 1965, distributors had points in them which had to be adjusted and or replaced periodically and the ignition timing needed to reset.
