Leerjet 85 or a Cessna Citation Mustang. 
So you're not sure if you want to take everyone and all their stuff or nobody and none of their things? If the 85 is half of what I expect it to be it'll be a hell of an airplane.
Gulfstream 550 for when I need to get wherever I need to go out of the CONUS.
Learjet 45XR for my <2000nm trips. 8 pax, full seats, full tanks, 10 golf bags and 10 overnight bags with room to spare.
Phenom 300 because I think it looks great.
F5 Tiger II for time critical missions.
If I had to pick one:
Dassault Falcon 7X. I'd get the type, fly it for a hundred hours and sell it. With that money I'd buy a set of matching Lear 45s, a P-51 Mustang, an F4U-4 Corsair and still have money left over to operate all of them.
