Exterior only. Collision on the Hachimoto's windscreen and the rollcages on the FAVs is disabled though, so you can sit in the driver position, but that was just because why the hell not. I didn't really see the point of adding an interior to any of them, since they're all just props, and an interior would just be a cramped space with a couple buttons. Besides, the only vehicle that could actually fit a comfortable interior (meaning you could actually stand up) would be the Goliath, and the only thing inside that is a cube with the vehicle's skin on it.
Also, I'd really like to know why people are saying no. Not because I think I deserve to get into the clan (I don't, it was Comr4de's idea for me to app with these), but because I want to know what is wrong with them. Yes I know they're awfully gray, that's because the server I built them on was using the default colorset.
