ROUGH RANGE

What N63NM might be worth, and where it’s heading.

A rough range: Radar's value model doesn't cover the Gulfstream IV (certified family) on its own yet. From Radar's listing-based estimates for business jets of similar engine thrust and age. The Gulfstream G450 curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
