Gulfstream G-IV
The G-IV had multiple names and derivatives during its long production. In 1986, it was an improvement on its predecessor the GIII. It retained the spacious cabin and signature Gulfstream profile but gained range and performance along with several aerodynamic tweaks and avionic upgrades. The G-IV can represent incredible value at purchase, offering a big corporate jet at often 20% of its original value. Many of these worthy aircraft have been meticulously maintained throughout their life.
