going to be getting a 64 comanche 250 8389P

I'd opt for a Comanche 260 (B or C models) with the fuel-injected engine
and a little more room in the cabin.

Just remember that the room in the cabin comes from moving the baggage
bulkhead back. The overall dimension of the plane is longer, but all
of the length is in an extended cowl which moves the propeller/spinner
farther out for CG purposes. The rear seats in the 250 are already as
far back as they can go. The front edge corresponds with the wing spar.
