ROUGH RANGE

What N128J might be worth, and where it’s heading.

A rough range: Radar's value model doesn't cover the Beechcraft King Air 350 on its own yet. From manufacturer-published new prices of comparable 2100 shp twin turboprops, depreciated for age. The Beechcraft King Air 350i curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
