I gave you a smart ass but yet very serious answer earlier in this thread. Over the past 20+ years of Mooney ownership, I've concluded a few things:
- Ownership is exceedingly difficult and expensive if you can't help yourself to some level. You have to get to know your airplane and you have to be able to spot issues, particularly issues that occur after major maintenance. Maintenance induced failures are real. IMO, owner assisted maintenance is essential.
- When I purchased my airplane, I spent an additional 30% of the purchase price on upgrades a few months later just to be somewhat satisfied with the flight experience. And... I had a pre-buy with a local mechanic.
- If you don't have a local mechanic that can do what he says he's going to do when he says he's going to do it (within reason), ownership is exceedingly frustrating. Even annual inspections can take a month instead of a week; and you'll have a few that take many months (4-6) when it comes to major issues (paint, engine overhauls, avionics upgrades, etc).
- My suggestion is to find a mechanic at your local airport that's willing to support you long term and help you make these decisions. Ask if you can help or at least observe maintenance and learn about your airplane. Make sure he's willing to work on a Mooney. If he doesn't want you on the shop floor (within reason), that's a problem in my opinion.
- I'm getting older and crawling around on the floor cleaning and removing inspection panels is getting harder. When I can no longer assist with maintenance or when a shop that can perform maintenance in a timely manner is no longer available at my home airport, I'm done flying.
You've got a lot of advice about the different aspects of ownership. I suggest you focus on maintenance next. Find a local mechanic before the purchase that can help you make these decisions and is willing to support you long term.
