I have around 1200 hours in the Avanti I & II and enjoyed the plane. It wasn't the most forgiving of aircraft, especially on the ground with a strong crosswind. The nosewheel steering was a total mess, it had to be engaged with the rudder centered or whatever input you had in would command an equal amount of steering input. I struggled with this initially as I was always reaching for a tiller from past experience in larger jets. Once you got used to it and developed a technique it was fine. Systems wise it was an interesting aircraft, especially the anit-ice system. The forward wing (not a canard) was electrically heated, main wing was heated via bleed air, intake lips had boots, and the props had no heat as the engine exhaust was supposed to do the job.
The original design of the aircraft was from the Lear family that was later picked up by the Italians with financial support from Ferrari. IIRC the company is now primarily owned by the Tata group which is Indian.
