The Citation II/SP cabin.
Illustrations of a representative Citation II/SP cabin, not N551NC’s. Every aircraft’s completion differs. Citation II/SP Model 551 exterior reference. Installed modifications, equipment, paint and cabin completion vary. View the Cessna Citation II model page. Compare with the Cessna Citation II interior reference.
ROUGH RANGE
What N551NC might be worth, and where it’s heading.
A rough range: Radar's value model doesn't cover the Cessna Citation II/SP on its own yet. From Radar's listing-based estimates for business jets of similar engine thrust and age. The Embraer Phenom 300/300E curve gives the shape of the forecast, and the range is widened to match. Not an appraisal.
