Doug,

Make sure your cost estimates are carefully considered. I don't know
much about the Comaches, but have owned a 1978 Arrow, 1984 Bonanza and a
1968 C-172. Vintage retracts can cost a lot in maintenance, even if the
initial price is low. Everyone who has bought an old twin sees this.

Did you consider a Cessna 182? It's probably more initially, but
insurance and maintenance will likely be less. Appreciation may possibly
be greater with a 182, so that's where you need to sharpen your pencil.
As an investor, I'd rather take my chances on a C-182 than a Comanche.

Also, if you pay $20k more for a C-182, yet $800 less in insurance and
$1000 less in annual maintenance, isn't that a better deal? Even if you
get different numbers, don't contaminate the initial cost estimate,
which you likely get back upon resale, with the operating cost, which
you never see back again.

You seem tilted toward a low-wing, which is easier to land in gusty
crosswinds, but a heavier high-wing, like the 182, isn't that bad.
Panel lighting on the Cessnas is generally primitive, but that can be
fixed. Also, two doors are great.

Good luck.
