They certainly were made in high volume. Flying is a compromise, and obviously what Cessna offered works (or at least worked for most people). I'm just not one of them. Incidentally we have a really well equipped 172 now in our club, pretty paint, nice avionics, electric MT prop.. good speed for a 172. I put about 10 hrs on it trying to love it (great price, looks nice) but when push came to shove I just don't like the way they fly.
Most of their twins looks great though, especially the 310, 340, and the 337. The 340 aged well, the 310 just looks fast, and the 337 has the utilitarian look to go with it. But I could never justify owning one any of them. For me those compromises don't balance out in my favor
Having said that, their classic tail draggers really do hit the mark of "this is what a light GA plane should look like" .. so there's that!
