I've never been too much of a fan of the whole idea of Genestealer Cults riding around in pimped out sedans like a group of Mafia Dons. The whole idea of the Genestealer Cult is that they are a hidden force, operating in the shadows until the time is right to make a bigger against their host society. Surely anything that draws attention to them would be a bad thing in their eyes, cool looking pimp-mobiles included.
Since the latest background for the Cult seems to focus on them taking over mining planets I thought a much better solution would be for them to ride around in whatever they could get their hands on. Hence the vehicle below. A salvaged mining vehicle, press ganged into APC duty.
