all the competitors are unable to go full-fuel-full-pax. CL 300, G200, G250, Sovereign- all the same.
If you are thinking of buying a new aircraft and money is not the issue, I would think of a Hawker 4000. Full-pax-full-fuel, and the luggage problem of the HS125 definetly solved. But don't buy one of the first serial numbers. And make sure that the new, redesigned toilet is available.
How can you compare a Hawker to a CL300, G200, G280? They are in different leagues, speed, range, cabin, hold, costs... Oh and possibly now product support.
