I don't know much about aircraft, but I know a little about this one.
It's a very cool looking corporate twin-turboprop airplane. I once saw one back up under its own power to get into position for its takeoff run at a rural airport.
The first-stage compressor blade circle is about the same diameter as the blower in a canister-style vacuum cleaner. Somewhat more expensive, I'll wager.
I always thought that ability to change prop-pitch to reverse thrust would make me a little nervous about flying in one. If it happened in flight it could really ruin your day.
