Does it have any damage history? I bought a 1978 J from Air-Mods that they rebuilt. They used it as a rental for 9 years before I bought it. It's a good airplane, but they had failed to do all of the paper work properly. An IA found the shortcomings, and deemed the aircraft not airworthy. Air-Mods helped get it straight, but had to go to the Mooney engineers to get it approved. With the shutdown of Mooney, it took a couple of months, and I doubt they would be successful now since Mooney has been closed longer. We had gotten to the point where they were going to buy it back from me, but finally got Mooney to provide the engineering needed. It was a nightmare. I also could not put a Garmin GFC500 in the airplane due to it has an L model tail cone. Air-Mods are good people, and good to work with, but be careful of rebuilt airplanes. I would buy from them again, but now know what to look for, and totally recommend a pre-buy inspection of the airplane and log books by an independent IA.
