i was thinking of the new 600 . not a used 650 = dp world can afford it for you.

Standard BID inside the cabin is 2,438 meters

I can=confirm our BBJ has the lower pressure kit installed. 1,981m=ters.

The New Boein= 787 is 1,828 meters.

The Gulfstream G650ER cabin is less than 1,239 meters.

The Gulfstream G650ER has the lowest cabin of all =ets. Almost half the cabin altitude of most airliners. <=iv>

Information below comes from the Gulfstream web site.<=font>

The G650ER cabin is replenished with 100 percent fresh air every=two minutes. And with the lowest cabin altitude in the class, matched only=by its sister ship, the Gulfstream G650, passenger heart and lungs can =ore easily oxygenate the blood, which reduces fatigue and ensures a mo=e alert and refreshed arrival many time zones later. At a cruise altitude =f 45,000 feet/13,716 meters, a G650ER cabin is pressurized to an altitude =f 4,060 feet/1,237 meters. That cabin altitude is almost two times lower t=an commercial airlines and significantly better than any non-Gulfstream ai=craft in the large-cabin class.

A side note: the G-650ER flies 6-12 =A0percent faster than the BBJ.

Max range BBJ 10,926 Kilometers

Maximum range G650ER 13,890 Kilometers

The only other large jet to get us below 6000 fee= cabin altitude is the New Boeing 787.
