I flew the A-4M (and other things) with the USN at VX-5 78-81 - and I absolutely loved it. It was a great aircraft to fly and operate.
If I was 20/30 years or more younger, I can think of no better job than flying these machines as a civilian - and surprising those flying Generation-X fighters with what an old and small A-4 can do.
The powerful leading edge slats were my only minor gripe - as they gave me the occasional headache from bouncing my swede against the cockpit sides because I pulled "g" slightly asymmetrically!
A-4's Forever, etc, etc...................
