One of my flight instructors had a friend/business associate that bought a Kodiak @ Oshkosh after only having flown 182s. The insurance requirements were insane of course. Also, know a guy with 70 hours who bought a Lancair with a 330hp engine. In flying it seems more readily to be a case of if you can afford it, you can do it.
I was in a Mooney @ 120 hours. I just did a lot of extra training--EMT, Tailwheel endorsement, Instrument & commercial rating in it when I had the hours.
