ROUGH RANGE
What N450MB might be worth, and where it’s heading.
A rough range: Radar's value model doesn't cover the Gulfstream IV-SP 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 7 Gulfstream IV-SP estimates on Radar. The Gulfstream G450 curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
