Today’s Top Pick is a 1978 Mooney M20K 231.

For those with a need for speed, this 1979 Mooney M20K 231 stands out from the crowd. Known for its sleek design and impressive performance, the aircraft is a compelling choice for pilots who want to get to their destination quickly and efficiently, whether for business or pleasure.

Powering the aircraft is a turbocharged Continental TSIO-360-LB engine with only 662 hours since a major overhaul.

Performance is further enhanced by a suite of valuable modifications, including a Merlyn automatic wastegate, GAMI fuel injectors, and intercooler, all working together to maximize speed and fuel efficiency.

In-flight weather information is provided by a Garmin GDL 69 XM Weather datalink, while a Garmin GTX 330 transponder handles ADS-B Out requirements.

For a comprehensive overview of engine health, an Electronics International MVP-50P engine monitor is also installed.

While the airframe has accumulated 5,155 hours, the aircraft has clearly been well maintained. A custom paint job gives it a sharp ramp presence, and the leather interior ensures a comfortable journey for the pilot and passengers.

Listed at $139,900, this 197 Mooney M20K 231 represents an excellent opportunity to acquire a technologically updated, high-performance aircraft. Interested buyers will find a capable and efficient cross-country machine ready for its next adventure.
