I may need to sell my 1986 252 due to pending medical issues. Surveying the market shows online 252's priced ~200K and above. Most have been on the market for the last 6-12 months and there are more 252/Encores on the market at one time than in the  past > 20 years. I can remember the time when a 252 would be gobbled up as soon as it hit the market. For whatever reasons (all speculative) the supply outpaces the current demand. Obviously an airplane is worth whatever a buyer wants to pay.
