I have a very clean 69 Arrow with 2200 hours, though some gear
collapse history. I recently considered whether to upgrade the Arrow
with STEC 30 and stormscope or purchase a new Cirrus and decided to
upgrade the Arrow.

A well equipped Cirrus will run around $350K. Interest alone on this
is over $2K per month. 10% depreciation runs another $3K per month.
Although it's faster than the Arrow, it accomplishes this with a fuel
burn that's 50% greater and an engine that won't run any better (most
PA28R users can run the Lyc IO360 LOP without GAMIs).

My maintenance bills are high since there are always things to do, but
the Arrow is still the better buy, which is why there will be a market
for a long time.
