Wasn't this same thing tried with Bellanca? Where there was an ownership group of dedicated owners that decide to buy the assets to make parts and update the fleet in the hopes they'd gain approval to start manufacturing again.
I like the idea of being a service center and becoming a hot rod shop. Buying/refurbishing the old. Adding mods, avionics, and paint. But I don't think that really goes far enough. The M-20 was designed in 1953. That's the biggest problem. They've had one model for 65 years. They were really close to making breakthroughs a few times. First with the 301, then more recently with the M-10t/j. If the M10 was a four place, or an option to enlarge to a 4 place it might have had more of a chance. It looked really sharp. Retractable just doesn't have the same luster in a 4 place as it once did. You have Cirrus, Columbia/Corvallis/TTX, and Diamond showing you can go pretty quick keeping the wheels down. Less to insure, less to maintain, less to remember. The overweight, forgetful, and aesthetically needy Americans of 2020 have passed the design from 1953 by.
