Gulfstream G450
Which Should You Buy: Gulfstream GIV or Gulfstream G450?
Bottom line: Choose the G450 for modern PlaneView cockpit, mandate-compliant systems and the youngest available large-cabin Gulfstream. Choose the GIV only for materially lower acquisition cost and accept the older avionics and mandate-upgrade investments.
Pick the GIV if…
- Budget matters — from $1,534,250 vs $3,944,760, you save ~$2,410,510.
- Faster cruise — 488 kts vs 476 kts.
- More inventory — 56 listings vs 35.
Pick the G450 if…
- More seats — 16 vs 14.
- Longer range — 4350 nm vs 4220 nm.
- Newer design — production from 2004 vs 1985.
