Minimum flight time to get your cert is 40 hours. You train in a fixed gear plane, wheels don’t come up.

To fly this he would need a complex sign off to fly the retractable gear/variable pitch prop and high performance sign off for having over 200hp engine.

It’s a lot of airplane for that much experience but only takes 5 hours or so to get those sign offs from your instructor. Bonanzas have a reputation -now- that keep people away from them until they are very comfortable with flying a complex and fast airplane.
