The airplane appeals to the wealthy captives of pop culture, who want something unique with a lot of sex appeal. The same people who bought the Beech Starship and DeLorean automobile.
There are more practical ways to get that 2500 mile range. It simply involves paying a copilot, which is chicken feed when talking about an investment of this sort.
If you absolutely need 2500 miles single pilot, buy a 25 year old Citation II and stick some FJ-44's on it, along with the aft tank mod.
