What you saying may have some slight effect, but it is minor compared to the
general price trends of all aircraft and complex retracts specifically.
Very seldom does the appearance of a new airplane have much affect on the
value of used airplanes.

And others have said, I don't see someone with a budget of $150K for a 170K
IFR bird cross-shopping late-model F33As/V35Bs with a new $300K airplane.
And I think may pilots, truth be told, want a retract even if there are
fixed-gear airplanes of similar performance. Light twins can seldom be
practically justified over a heavy single, but many folks just get more
pleasure out of flying a twin. Finally, a Bonanza is a much more
rugged/substantial airplane, a much better rough field airplane, has a much
bigger baggage area, is bigger/heavier and arguably more comfortable, and is
a better airplane for situations where you can't hangar - I'd consider
hangaring an absolute requirement for a composite airplane.

I'll admit I'm prejudice, but I just don't see 25-year-old SR22s holding up
like 25-year-old Bonanzas have.

That's not to say that SR22s and Columbia's don't have their advantages.
They're fast, sleek, quiet, probably safer, and have absolutely gorgeous
panels. If I had $300K to spend, I'll look at them very seriously.
