According to Avpro, Inc. there are now 40 Citation Excels available for sale, up from the 38 that were available this time last year. It has been a relatively stable year, with the supply of excels increasing throughout the year, but then stabilizing somewhat when buyers swooped in to buy at reduced prices at the end of 2010.
The XLS market is doing much worse. More and more aircraft are becoming available for sale, but few are being bought, and this is causing a continued decline in prices.
