I dont care what you think they market it as....nobody buying an airplane thinks a Falcon 2000 is a "large cabin"....just sit in one for 5hrs and see.
It certainly isn't marketed to compete with the traditional Global/G5 aircraft, in fact nothing Falcon makes does....and I never heard anyone at Dassualt make such a claim...Falcon lives off of buyer loyalty (largely based on market preservation) and nothing else.
You guys gotta put down the free aviation magazines/surveys and de-dork yourselves.
