Thanks for the answers.
For sure the Learjet is a good option and here there are a lot of them flying.
About the landing gear is an upgrade of the lj 35 and 55.
In older post I`ve read about the mantenience of the Cessnas as a drawback, but I would like to check that info.
The plan is to fly 4/5 and plenty of luaggage to 2000 km legs.
