Line Up and Wait
You know, I don't consider all of those "improvements." My old straight tail 172 was way more fun to fly than later models, O-300, narrow gear, and all. In fact, as a more experienced pilot and aerial photographer I happen to prefer the narrow gear.
Agreed - personally, I love the O-300, such a reliable and smooth engine. And the manual flaps? Yes please. I'm in a 172S G1000 arrangement now and I still prefer many many things about the early 172 models over it. As others have mentioned, some of the worst planes I've been in were the rental line late 90's models such as the 172R.
Heck just look at all the DHC 2/3 running these days up in the bush...
