I don't get the P2006 for a private owner. If you are over 55 years old, for the price of a P2006 you could get a nice Baron/Aztec/Cessna 310 and pay for all the fuel and maintenance for the rest of your flying life and still be ahead.
Only if you never fly it, BPF. At just 100-150hrs per year, the Tecnam will be cheaper to own, even when financed, compared to a paid off dinosaur twin.
I've done the spread sheet.
