Well, then, this year's "annual" cost me:

$550 for the cylinder inspection and repair/replacement of the exhaust valve
and a ring set
$350 for the muffler replacement
$190 for the muffler shroud repair
$125 for the wash/wax job
$150 for what I would have charged me for the "annual"

But how much of this is "annual inspection"? $150. I could have done all
that other stuff any time during the year. As you say, it was a hell of a
lot more convenient while the airplane was apart, but it isn't part of the
annual inspection.

Not to mention vacuuming the rugs and painting the dings and the prop.

Sure there is. The popular usage of the term "annual" is that
fun time of year when an annual inspection occurs, plus all those
repairs, service, and improvements made to the airplane.
Not to mention the "while-we-are-at-it" things.
