ROUGH RANGE

What N121EF might be worth, and where it’s heading.

A rough range: Radar's value model doesn't cover the Gulfstream GVI (G650ER) on its own yet. From Radar's listing-based estimates for business jets of similar engine thrust and age. The Gulfstream G650 curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
