I had one stolen once. I built a 1967 Comet Cyclone as a funny car back in 1967. I altered the wheelbase and built a tubular frame from sections of sprue - did lots of scratch building on it, painted it metallic purple. It was the best model I had ever built back then. I had it in a hobby show at a local fair, along with about five other models. They won first prize, but when I went to take the models home, the Comet was gone. The displays were locked behind chicken wire, so no spectator took it. It had to be one of the other exhibitors. Of course, the people in charge of watching the displays saw and knew nothing! I never saw that model again.
