Dennis:
What's the local market for 2-place airplanes like?
Maybe you could set up a LLC or partnership and sell 3 shares at $7.5K or 4 shares at $5.5K. That would give you close to your current asking price and you could take the money and hike on out, or keep one share for yourself, have some of the money, and still have access to an airplane with reduced fixed costs.
