That said, I could see the Princess at 40k being about right, if on the far low end of "about right", since it is just some luxurious stuff in a relatively small ship using common civilian tech. It's a S600 Maybach, not a Globalyst G6. Performance upgrades are always more than the base price because of diminishing ROI, so getting every last bit of performance out of an Impulse is a lot more, even if its tiny. And again, lower production runs, less customer base, etc. compound miniaturization.
