The only little problem of the avanti is the poor cargo area, if your passengers are carrying big bags, this will be a problem....
You won't have it with Beechcraft.......
If you are looking for a new aircraft....the 350 is still in production and the cockpit is well equipped with Proline 21, with this aircraft you have 85% of the speed of the avanti with all the advantages of the beechcraft family (including landing on short fields....), and the good thing is that both aircraft are more or less at the same price.....
