Prospective aircraft buyers often look for private jets for sale by searching Google, gathering information on various makes & models and their performance characteristics, and on condition, age, price and other information about specific jets for sale. Most private airplane buyers use standard phrases like: "private jets for sale", "private jets on sale" or "private jets on market" for their search. Some prefer more specific terms that may include a manufacturer’s name along with the aircraft model number, and configuration features such as a particular upgraded avionics package. Searching for aircraft for sale online using very specific terms may miss some listings due to variations in identification, for example “Gulfstream G550” vs. “Gulfstream G-550.” More inclusive searches, such as “Gulfstream, large-cabin jet” yield more results.
