Aside from inferior products, it's that attitude that has cost Gulfstream a signifigant market share over the past few years. Gulfstream has great products, but they are not the best. 10 years ago, the Gulfstream products were only aircraft with general recognition as a "status" aircraft. That has changed in the past few years. A few years ago, a casually dressed man (was not an aircraft owner) tried to get onboard a static GIV SP at NBAA. He was denied the walk-through because he did not have an appointment. How silly is that. Today, he is on his second aircraft, a GLEX, and he paid for it himself becasue he did not want to burden his company with the expense. In all fairness, Microsoft could have carried that weight, no problem. Or Walmart; A few years ago they bought a GIV (S/N 1 I think). At the time, support for the aircraft was non-existant from Gulfstream. The aircraft was promptly replaced with a Global. Once again, attitude determines your altitude.
Gulfstreams are nice, but there are bigger, more expensive, longer range aircraft that shame gulfstreams. Personally, I would reccomend a GLEX or 900EX before a Gulfstream to a potential buyer. Seems Bombardier and Falcon have figured out that a big 'ol fat slat hanging out there does more good than bad. Wonder what Gulfstream is waiting on????
