The Cessna Citation XLS+ (316.517.6056, www.cessna.com) offers the agility of a light jet and the roomy interior of a midsize one. The cabin is nearly 19 feet long, 5 feet 6 inches wide, and 5 feet 7 inches tall. It accommodates nine or 10 passengers in wide seats with drop-down armrests. The interior and exterior baggage compartments together measure 90 cubic feet, which is the most stowage of any jet in this class. The aircraft’s runway performance is also a selling point. It can take off from runways as short as 3,600 feet, and it can achieve unusually smooth landings thanks to its high-capacity carbon brakes. For all these reasons, the $12.75 million Citation XLS+ tends to retain most of its value in the secondary market.
