Hi Larry,
I just bought a 1979 Turbo Arrow, 1450 TTAF never used as a trainer. I would definitely look at repetitive 100 hour inspections, and give you the ATC advisory, “Caution Wake Turbulence”, an issue may or may not be there but heads up.
I came upon this thread late, did you buy or still looking?
