Think about it really. The best market for detailing services are to those that don't have time for it, and are willing to spend a pretty good penny to have it done. Most people that own a classic car, and go to a show obviously have some time on their hands. And typically I think most of the attendees have restored the car themselves also. So as was already mentioned, you will probably have a hard time selling your services to this crowd. Now a show like Pebble Beach, or the like might be a different story I think. But there you have such valuable cars, it might be tough to get them to let you use a machine on them.
