ESTIMATED VALUE

What N18243 might be worth

Rough range$3.6M to $9.9M

A rough range for a 1999 airliner, with a middle of about $6M. From Radar's listing-based estimates for airliners of similar engine thrust and age. It is not an appraisal and knows nothing about N18243 itself: total time, engines, condition, equipment and the logbooks move the price of any one aircraft.
