Looking at buying into partnership or alone, generic Cessna 172 /182 circa 1965-75. Assuming lower engine time, decent interior. I'm thinking if I've got 15-20k to spend on upgrades, would it make more sense to get a chute vs. panel upgrade? Love the panel upgrades but moderate increase in safety. Any chute folks out there? (Esp those w Cessna chutes). Compare chute "value" vs. panel value on resale?
