I used spare plastic from the kit, a cereal box for floorpans, electrical wire for the steering wheel and roll cage, a toothpick and a ball of tape as a shift knob and some packing foam for a seat. Belt buckles are the wiper decals from the kit traced with a red sharpie. Gauges are decals from the kit and a sharpie. and a bit of glue. Crude and cheap but it took under 2 hours while watching tv. Good place to store a body
