Speed/handling meh, the rigger drives it, so who cares. As far as inconspicuous, it's called morphing license plate, spoofing chips, and cemeleon coating. Now it can be any armed car or moving van you want. Plus, with body its high body, you have more mod slots than nearly any other vehicle on the market. So go ahead and raise its speed and handling a bit, add in grid-guide override and manual control override, and any other fun mods you want. Then you still have slots for drone racks, concealable weapon turrets, gun ports, extra armor, run flat tires (or street tires for more handling), and winch.
