Wrap around rear window, one piece front window, Johnson Bar flaps, O-300... the D is right in the sweet spot of that vintage of 172. The E got circuit breakers but who cares? Carry some spare fuses.
That'd be one honest little 172 to do some puttering around in, and about as cheap flying as it gets.
Polished is neither here nor there for me, and it means some more work, but I don't need much of an excuse to say I want to go do something at the hangar even if it's not actually flying.
I couldn't tell ya what it's supposed to cost these days but at $25K with new jugs and old radios, it wouldn't take much to fix the radio issue and make quite a little personal workhorse out of a D model. There are a lot of cars that sell for lots and lots more than that.
But folks get weirded out by shotgun panels and old stuff. They seek to forget it's an Skyhawk. It'll fly just as well or better than the fat heavy new ones. And the Johnson Bar is way better for flap actuation than anything Cessna ever came up with after those.
I have a couple of hours in an A model and I wouldn't hesitate to own any of those up through E.
F added the electric flaps and while not awful, that gets a "meh" from me in that vintage.
Someone should buy that thing and fly the hell out of it. It'll need some radio love and something to deal with ADS-B in a few years, or not... but you could go simple or fancy with that panel and it's still just a 172.
