I just looked at it realistically. Professional mercs who risk their lives get paid a lot of money. Usually around $200-$300k/year + bonuses for specific tasks. For that pay they give up to the patron all loot. So any high priced items like vehicles, powered armor, etc. are owned by the patron.
I translate that to (PC lvl)x($1000/wk). 1st lvl PCs get paid $4000/month. 10th lvl PCs get paid $40,000 a month
Vehicles and such are just signed out at item level as Security Clearance or Underworld Reputation level.
This keep the players from Murderhoboing to make a living and is frankly more realistic to a future economy. Because people don't make a living looting the bodies of the people they kill. And. It's important to have a patron because killing people is ILLEGAL.
