Some can't afford to buy a brand new a used but decent enough ship. Prices peaked drawstically lately. But if you are knowledgeable enough and/or have a few skilled people at hand, you can build your own from parts either gathered in scavenger hunts - or raids, if the individuals are pirates of sorts - or around market places etc. At least that is the trend lately. A good way to to make things match a little is to give the whole thing a paint job.
