208 Kts at 20,000 ft using a total of 23 USG/hour.
Service Ceiling of 25,000ft.
Meticulously maintained and operated for the last 29 years by current owner who has been the president of the International Comanche Society and has in-depth knowledge of the type.
Very low engine hours.
Updated avionics including Garmin suite GTN 650, 2x G5s, GTX330ES with ADS-B out (see full list in Avionics section below) and many extras (see detail below).
