The best way to become a wealthy individual is to make wise financial decisions.
I am totally in love with the Extra 500 but even if I could afford it at €1.3m + VAT, I would probably not do it.
Precisely. There's just a certain limit to frivolous spending & diminishing returns on satisfaction. C'mon, the most enjoyable trips I've ever taken certainly weren't done in the fastest or most expensive aircraft. Enjoyment doesn't scale well w/cost or speed.
Not to mention that you really need the *time* to fly these USD1m+ aircraft. The TP & jet owners I know are all either (semi-) retired and/or use their aircraft actively for business. If I had a USD3m+ TBM850 sitting idle on the ramp 95% of the time, I'd be friggin' miserable on a daily basis.
