ROUGH RANGE

What N302SB might be worth, and where it’s heading.

A rough range: Radar's value model doesn't cover the Gulfstream G550 on its own yet. From Radar's listing-based estimates for business jets of similar engine thrust and age, set to the level of the 5 Gulfstream G550 estimates on Radar. The Gulfstream G650 curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
