160kts in a cleaned up Comanche isn't vapor -- that's only about 185MPH.
It's not even uncommon. I see speeds like that all the time in my
slightly-cleaned-up (Lopresti and Knots2U) 250 -- speeds that I'm
confident in because we were positively anal about evaluating each mod
that went on (and in some case, subsequently came off) the airframe.

3. Mooney seems to be emerging from their financial troubles, and
believe it or not, may own Beechcraft soon. Comanche parts are
becoming a bit difficult to find and added to the fact that the
aircraft is no being produced worries me. Also, a good Comanche
mechanic is a must if you want to keep the aircraft in the air. Good
luck.

I've yet to find a Comanche part that wasn't available or couldn't be
fabricated by Webco or Johnston. That includes every bit and piece of
the gear system, stabilator trim tabs (had to replace one when
installing the Vne kit), aileron skins (an L-39 got dropped on one of
mine while my aircraft was undergoing a year-long refit), fuel cells and
other random bits-and-pieces. While it might take someone with
particular Comanche mojo to keep a 400 in the air, I've had no issues
with a 250 with a combination of doing my homework and otherwise
competent mechanics.
