Gulfstream G450
The G450 is the final development of the Gulfstream IV family. 365 were built between 2004 and January 2018, which makes it one of the most widely available large-cabin jets on the pre-owned market.
What to check before buying
Ask when the next major calendar inspection falls due and budget for it, check whether the Tay engines are on Rolls-Royce CorporateCare, and confirm the avionics meet current airspace mandates for the routes you plan to fly.
Dassault Falcon 900LX
The Falcon 900LX is the current version of the three-engine Falcon 900, with blended winglets that extend range to 4,750 nm. Three engines allow more direct routes over water and remote areas.
What to check before buying
Three engines mean three engine programmes: check Honeywell MSP coverage on all of them, and compare time to the next hot-section inspection.
