I'll agree with Andrew on this one. John's Mooney is as nice as you'll find, and plus that little turbo engine is a really sweet option in my opinion. The one thing I really wished that the Mooney I flew had was a turbo. I've even personally witnessed that particular Mooney land on a grass strip.
As to the not small comment, I believe that John's is a "widebody" Mooney. The M20F I flew (also the wider one) was not short on interior space. While I'm pretty thin, I've flown in it with plenty of "not small" people and never felt too close for comfort. Although if they hadn't showered in a few days I might have felt differently.
Grant, spend money you don't have to buy something you don't need. This has been a public service announcement.
