I think I’d avoid the trainer if it was me. I flew these at ERAU when they had them in their fleet from around 1991 to 2001. They were used for commercial complex training. It was usually one lesson of stalls and slow flight with each student and then right to the pattern for practice work. High gear usage, and lots of hard landings - you had to touchdown within 50 feet of your designated point...with a student with around 100 hours total time flying a Mooney...YIKES! Riddle did a great job maintaining them, but the airplanes were really used up after 10 years of this routine. This is also the M20J ATS which was a stripper model, which was available to flight schools from 1989 to 1992 or so.
