If you look at the car industry there are luxury comfort brand like Rolls Royce or Bentley but super expensive racing cars are probably even more popular. They offer limited comfort, are not practical, almost not usable on normal roads, not very reliable and offer terrible fuel consumption. But still everybody dreams about them and a lot of companies try to manufacture.
Business jet can offer luxury and comfort but what to do if you want some excitement or performance? Why are there no jets with massive after burning engines with thrust bigger than weight that can climb straight up and do several G? Something like a cross-breed between a Gulfstream and an F15? Maybe it's good business case to manufacture something like this?
