Malibu Mirage ?
Guess it depends on what you are currently doing ? Most of these operators learn quickly that it is a very limited plane. Sure it is pressurized, known ice, and fairly fast however there are many a pilot that will never get a second chance at that go/no-go decision. I have flown them, pretty complex pressurization system, not in the operation but in the reliability, asking a lot from a single engine.
Pros - nice engine over the straight Malibu, good speed, nice avionics, pressurization, de-ice, excellent glide ratio (15/1), and most have nice interiors.
Cons - too many to list however here are a few that stand out, the Lycoming won't make TBO - plan on about half, owners think they are flying a jet in that they can go anywhere any time, slippery airframe so descent planning very important, short coupled gear, and expensive as a turbine to overhaul.
Nice VFR and limited IFR plane but one has to know this flying one. Still a single engine plane. Get the speed brake mod, will really save on the shock cooling of that engine, very sensative. Speed brakes give you about 1500" per min. with the power left at cruise setting.
Bottom line if the owner/company that is buying it has the HP to buy a bigger plane with a turbine or even a C-421, they will see the light eventually or they won't, if you get my drift. What kind of cargo job did you say you were contemplating ? Most have two motors.
