RADAR ESTIMATE
What N18GJ is worth, and where it’s heading.
Radar's value model doesn't cover the Learjet 45 on its own yet, so this borrows the Cessna Citation XLS+ curve, scales it to N18GJ's listing-based estimate and widens the range to match. An estimate, not an appraisal.

RESEARCH NOTES
About N18GJ
Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.
Overview
This entry covers airframe N18GJ, a Learjet 45 with manufacturer serial number 45-442 currently held by G & J Holdings LLC (Co-Ownership) based in Lafayette, LA, US. Ownership is recorded as a co-ownership arrangement, and the aircraft’s registration and documented cabin capacity are the most notable registry details available for this airframe. Maintenance condition and specific modification history are not published in the supplied data.
Operations & Cabin
The interior is described as a typical executive layout with double-club seating commonly accommodating eight passengers, complemented by a forward galley and an aft belted lavatory; registry listings, however, indicate 12 seats for this specific airframe. Avionics fit is the Honeywell Primus 1000 with a four-screen EFIS, a common factory/retrofit configuration on Learjet 45/LJ45XR models, supporting standard business-jet navigation and flight management capabilities. Typical missions for this configuration would include short- to medium-range executive transport and on-demand charter work within the aircraft’s approximately 1,971 nm range, operating from the owner’s base in Lafayette, LA, US. No additional unique cabin amenities or bespoke interior modifications are documented in the provided dataset.
Model & Market Context
The Learjet 45 family occupies the light-to-midsize business-jet niche, offering high cruising speed (here 436 kts) and a high-altitude ceiling (51,000 ft) suitable for rapid point-to-point travel. Competitors in the same market include other light-cabin jets with similar missions and range, and buyers typically weigh factors such as avionics suite (this airframe’s Honeywell Primus 1000), operating costs, and fleet commonality.
