Alot of bonanza parts are expensive.

Aircraft parts in general are expensive; Beech parts are simply
outrageous.

My injected engines have one way valves that allow fuel to drain in
case it was overprimed. They are Piper parts, and are $50 each. They
are functionally equivalent to automotive valves that cost $10 each.
But that's nothing. My friend has a Baron, and his valves are $600
each. That's the Beech way.

Similar example - rod ends for trim tab actuators. Normally an AN
part, about $15. On the Baron, it's $120.

Most of the Beechcraft parts are very well built and don't need changing
very often.

Many of my friends own Bonanzas and Barons. I have not noticed them
replacing parts less often than I do on my Piper, same vintage. Beech
parts are no better (or worse) than any other aircraft parts. They are
more expensive.

Once the aircraft is up to snuff, the maintenance isn't much different
than other aircraft of the same type.

That's true. Mostly, the parts that wear out are engine, not airframe
parts. Fortunately, the engines are Continental - not Beech/Raytheon.
By the time you figure in all the other expenses - labor, engine parts,
fuel, insurance, hangar, engine overhaul - the high cost of Beech parts
isn't really a significant factor in owning a Beech. It's only when
you buy something that needs a lot of airframe work that the Beech
parts cost hits you hard. That's why you can get such a great deal on
an old Bonanza, Baron, or TravelAir.

Nothing flys like a Bonanza!!!

Actually, lots of things fly like a Bonanza. It's an airplane.
Nothing special.

The real truth is, nothing lands like a Bonanza. Most airplanes in its
class require some skill to land. The Bonanza really doesn't. It's
easier to land than a C-172. It makes you look good. That's why so
many pilots love it.
