Opps, sorry about that.
Aerohack has correctly provided the gist.
This is the conclusion of the article:
Which leads us to the inevitable question: Are these 50-year-old airplanes worth owning? Or have they simply outlived their economic usefulness?
Early straight 35s are selling in the $30,000 range with As and Bs a bit more, in the mid 30s. Those sound like good deals, but just because they’re cheap to buy, they’re not necessarily cheap to own or maintain. The ugly reality is that some owners paying only $30,000 for an airplane expect $200 annuals, and this simply isn’t realistic for a Bonanza. And if a poorly maintained model gets its tail twisted due to ruddervator imbalance, it might be uneconomic to repair.
Our advice is avoid these models unless you can find an obviously well-maintained example and you’re willing to keep it that way.
Many people would tell you that Bonanzas are simply the finest personal airplanes ever made, so don't be too discouraged. But one thing that seems to be indisputable is that all Beechcraft parts are very, very expensive
... so that has to be factored into the estimated maintenance costs, even for the cheaper/simpler Beech singles like the Musketeer.
