Thank you everyone for the suggestions. The Praire Cat ended up winning out, but knowing this group, that vehicle will probably get destroyed in Chicago.
As for such a large group, it's currently 9 PCs and 2 rotating NPCs (the hackers, one AI one technomancer). And while combats can be a bit slow going, the overall flow is going pretty well. It's just a matter of keeping the people at the table on track with the game.
