Regarding rules for vehicles, I don't really know how I should approach it. The way I see it, in a system this lightweight a lot of it is already covered by basic skill checks.
Having rules for quickly creating NPCs could be useful, I'll consider it. Maybe I will write a separate manual with enemies, could be interesting.
When it comes to coverting prices, apart from cyberware and cyberdecks, I think most items could easily be translated with a 1:1 conversion.
