I worked for a company that was an early adapter with the G200, I think we had 6 of them at one point in the mid 2000s. They aren't the prettiest airplane, or the greatest performers but for a super midsize they do pretty well. As long as you take care of them they are pretty reliable. Eventually you will have flap/slat problems, leaky flight control actuators (have your maintenance guys check the leak rate in the AMM before replacing them, they're expensive and I've seen new airplanes getting outfitted in Dallas with leaking actuators), and if it still has black deice boots you'll probably need to be replacing them sooner rather then later. The black ones were phased out a long time ago and are probably nearing the the end of their useful life just based on their age, and the silver ones look better anyways. There is a BFGoodrich facility somewhere in Ohio(?) that can replace them in a little over 24hrs for about half of the cost of what Gulfstream charges just for parts. It's just not as rugged as a real Gulfstream and you might find that your maintenance people won't like working on it because it's completely different, kind of like asking a Lear mechanic to work on a Hawker or vise-versa. If it doesn't already have it I'd strongly suggest getting the LED nav light ASC, the incandescant tail lamp can't survive the vibrations and the wingtip lamps must be made of moon rocks based on what they cost. Also, do yourself a favor and make sure everybody reads the manual for the door (first airplane I've ever seen with a seperate manual for the door), that thing can get stuck partially open and cause some expensive damage, not to mention it's quite capable of removing fingers. (Pro-Tip, do the thrust reverser secondary latch clean/inspect/lube frequently, it will alleviate some nuisance FADEC caution messages.)
