JABAG the G3000 upgrade costs $357950. The question you need to ask is 'what extra capability do you get for your money?' Great aircraft though. Performance, cabin, cockpit all make a CJ4 look pretty poor. Has the feel of a much bigger aircraft when you fly it. Some pilots complain about the turning circle when taxying, might be something to check if you often park on congested ramps. Enjoy your new jet. McD
