No idea. I love mine. Great plane.

I expect that the number for sale at any one time fluctuates. Be happy that there is a good selection to choose from at this particular time.
I bought mine officially almost a month ago. Since that time it has been delivered by a Mooney transition instructor who has signed me off and she is tucked away safely. If it weren't for 12G20 direct crosswind right now I would be in her building time right this minute. I will build up to a diect gusty crosswind in due time.
"Joyce" is a great, manual gear, corrosion free, fresh total time engine and prop, 430W, freshly painted example. I am sure there are other such examples out there. I am also sure that there are corroded, leaking fuel tank, tired engine,...... et al. They are a somewhat different breed than the more common Beech/Piper/Cessna aircraft that commonly represent the General Aviation fleet. They are clean, fast, fuel efficient and precise handling, thanks to the control rods versus cables of most planes as well as the genius of the late Al Mooney.
If you are not so large that you won't fit into one(although they have more room than the Mooney mythology indicates,) you like efficiency and precision along with system simplicity AND you have access to a Mooney savvy A&P/IA, then it is an aircraft worth looking into.
From what I have seen over the years people either love or hate a Mooney. I also have discovered over the years that the typical Mooney hater is someone who has either never been inside one or have limited experience. Maybe someone needs to compile a book of Mooney Mythology. If they do, the first myth on page one will probably be "you wear a Mooney." My girlfriend and I are average size and fit into it quite easily.
