Gulfstream IV (certified family)

Radar's rough range is about $7.4M to $17M for a 2004 and $2.7M to $6M for a 1986. From Radar's listing-based estimates for business jets of similar engine thrust and age. These are rough ranges, not appraisals: hours, engines, damage history, equipment and the logbooks move the price of any one aircraft.

What moves the price of any one IV (certified family): total time and engine time, engine program enrollment, damage history, avionics and equipment, and complete logbooks. Build year sets the baseline shown on this page; a IV (certified family) with high hours, an engine near overhaul or gaps in its records sells below it, and one with low time, recent inspections and full records above it.

Radar does not list aircraft for sale. It tracks all 125 US-registered IV (certified family)s by tail number, each with its registration record and a value estimate, so you can check a listing against the value of its build year and look up the aircraft's own history before you call.

125 IV (certified family)s are on the US civil aircraft register (FAA file of October 2026), built 1986 to 2004. Aircraft registered in other countries are not counted. Radar has a page for each US registration.

Of the 125 US-registered IV (certified family)s, 121 (97%) are registered to companies, trusts and other entities and 4 to individuals. Radar names entity owners only; individuals are shown as privately registered. The most common states of registration are CA (24), FL (19), DE (16).
