Gerald, I've got an M model for sale. It's been for sale for a while, since I've been putting zero effort into getting it gone. I guess I need to get off my duff and either sell it or fly it.
Nice paint and interior. Engine is less than 60 (sixty) SMOH. Dual radios with glideslope and marker beacon (and Loran boat anchor). Flies great (I've been to Sacramento and back in it). Asking $24,000.
The engine overhaul was mostly documented
in this thread.
