Flying in Europe is a slow game. It is incredibly cool to be just about anywhere in Europe within 4 hours, from Croatia to Sweden to France and Poland.
The downside is that everything is ticky-tacky. There are a million rules for everything, airspace is choked to death and the system is incredibly legalistic, theory-driven and downright expensive.
Flying in the US is indescribably different.
Easy, fun, and so open. Don't want to talk with anyone today? Don't. Want to zip over to wherever? Go for it.
Not so in Europe. Every trip is planned like an IFR flight, with full details, times, communication and so on.
Sweden, Norway and the northern regions where there are still wilds, are different. There, they, like us, care more about the aviator than the regulator.
So, I can highly recommend these two fantastic countries for the American pilot to have fun in.
The rest... just work, more work and nothing but the work. The destinations make it worthwhile though.
Oh, and speaking of maintenance: I took my 'J in for an annual at last minute b/c I was pressed for time one year. $7500 for the annual.
They replaced the gear harness (for no reason, it had just been replaced) and slapped stickers everywhere "Do not push, etc." and then a regular annual.
Seven. Thousand. Five. Hundred. Dollars. yeah.
ACG isn't like that. They're German, so it isn't as cheap as the US, but I trust everything they do. Great guys in the hangar, they're Mooney experts, can source parts and generally like flying. They have flown in the US and appreciate what aviation can, and should be.
I do recommend flying in Europe if you have too much money and time and don't know where to put it all...
Get either a fold-up bike (Quiggle) or an E-Scooter (what I do) and you can fly just about anywhere and have fun.
