I haven't had any luck showing the cars so far... It's muscle cars/rat rods around here. One of the reasons is, no one knows anything about them. So, I am having the advertising guys at my work do a couple of posters for me with the history. I will display it with the cars next year and see if that helps. The younger guys know what they are, but the old guys just walk on by...
Now, at the race track, whole different story. In the pits, they are surrounded most of the time after a run. I haven't been back this year, still working on the car, but hope to get in the last week this year if everything goes OK... So, just depends on your location, and interests of the car crowd...
