Wheel, sticks, radio and other gadgets are mostly from two sets of 1/35 Tamiya Willys Jeep. The red piece is an upside-down truck dump bed from a kinder surprise toy. You can slightly notice an actual small electronic button on the right, with guitar sting coming down as for cabling.
On the reverse angle, gray pieces are from a sci-fi terrain sprue (Special thanks to Burak) acting as some consoles. On the corner, a microphone end is used as ventilation with supporting pipes made from cotton swabs.
Eye-level shot of the interior. With the windows cut from clear plasticard and placed, interior looks pretty much done. Need some decoration around the exterior of the door.
